Questions and Answers

1.

Sound travels fastest in air because the particles are spread furthest apart.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
This statement is false because sound actually travels fastest in solids, not in air. In solids, the particles are closely packed together, allowing for faster transmission of sound waves. In air, the particles are more spread apart, which slows down the speed of sound.

2.

In a sound wave, the places where the particles are furthest apart are called the:
- A.
  
  Compresssions
- B.
  
  Rarefactions
- C.
  
  Wavelength
- D.
  
  Amplitude
Correct Answer
B. Rarefactions

Explanation
In a sound wave, the places where the particles are furthest apart are called rarefactions. This is because rarefactions are regions of low pressure in the wave where the particles are spread out. In contrast, compressions are regions of high pressure where the particles are closer together. The wavelength refers to the distance between two consecutive points in a wave, while the amplitude represents the maximum displacement of particles from their equilibrium position.

What is the correct relationship for the pitch and frequency of sound?
- A.
  
  The higher the pitch, the higher the frequency.
- B.
  
  The lower the pitch, the higher the frequency.
- C.
  
  The higher the pitch, the lower the frequency.
- D.
  
  There is no relationship between pitch and frequency.
Correct Answer
A. The higher the pitch, the higher the frequency.

Explanation
The pitch of a sound refers to how high or low it sounds to our ears. Frequency, on the other hand, is the number of vibrations or cycles per second that a sound wave produces. In general, higher-pitched sounds have higher frequencies, meaning that they produce more cycles per second. This relationship can be observed in musical instruments, where higher-pitched notes are produced by strings or air columns vibrating at faster rates. Therefore, the correct relationship is that the higher the pitch, the higher the frequency.

What is the correct relationship between the amplitude of sound and the volume?
- A.
  
  The louder the sound, the smaller the amplitude.
- B.
  
  The louder the sound, the higher the amplitude.
- C.
  
  The quieter the sound, the higher the amplitude.
- D.
  
  There is no relationship between volume and amplitude of sound.
Correct Answer
B. The louder the sound, the higher the amplitude.

Explanation
The correct relationship between the amplitude of sound and the volume is that the louder the sound, the higher the amplitude. Amplitude refers to the maximum displacement of a sound wave from its equilibrium position. When a sound is louder, it means that the sound wave has a larger amplitude, indicating a greater intensity or energy. Therefore, as the volume increases, the amplitude of the sound wave also increases.

For transverse and longitudinal waves, the higher the frequency...
- A.
  
  The longer the wavelength
- B.
  
  The shorter the wavelength
- C.
  
  The wavelength remains the same
Correct Answer
B. The shorter the wavelength

Explanation
In transverse and longitudinal waves, the frequency and wavelength are inversely proportional. This means that as the frequency increases, the wavelength decreases. Therefore, the higher the frequency, the shorter the wavelength.

Many rays of light make up a beam.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
A beam of light is composed of multiple rays of light traveling in the same direction. Each ray of light in the beam represents a distinct path that light can take. Therefore, it is true that many rays of light make up a beam.

7.

The Law of Reflection states that the angle of incidence is equal to the angle of reflection.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The Law of Reflection states that when a ray of light reflects off a surface, the angle at which it approaches the surface (angle of incidence) is equal to the angle at which it bounces off the surface (angle of reflection). This principle holds true for all types of reflection, whether it is light reflecting off a mirror or sound waves bouncing off a wall. Therefore, the statement is correct.

Ray boxes in Science are used to _________ the path of light.

Correct Answer
trace
observe
view
see
show

Explanation
Ray boxes in Science are used to trace, observe, view, see, and show the path of light. These devices emit a narrow beam of light that can be directed onto objects or surfaces, allowing scientists to study and analyze the behavior of light. By tracing the path of light, scientists can understand how it interacts with different materials and surfaces, observe its reflection and refraction, view its dispersion, see its formation of shadows, and show its properties and characteristics.

A concave mirror causes the light to diverge.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
A concave mirror actually causes light rays to converge, not diverge. When parallel light rays hit a concave mirror, they are reflected inwards and meet at a focal point. This property of convergence is what makes concave mirrors useful in applications such as focusing light in telescopes and creating magnified images in shaving mirrors. Therefore, the correct answer is False.

Refraction of light occurs because the _______ of light changes as it goes from one medium to another.
- A.
  
  Angle
- B.
  
  Speed
- C.
  
  Direction
- D.
  
  Frequency
Correct Answer
B. Speed

Explanation
Refraction of light occurs because the speed of light changes as it goes from one medium to another. When light passes from a medium with one refractive index to another with a different refractive index, its speed changes, causing it to bend or change direction. This change in speed is responsible for the phenomenon of refraction.

A diverging lens is one that has a ____________ shape.
- A.
  
  Biconcave
- B.
  
  Biconvex
- C.
  
  Flat
- D.
  
  Irregular
Correct Answer
A. Biconcave

Explanation
A diverging lens is one that has a biconcave shape. This means that both surfaces of the lens curve inward, creating a thinner center and thicker edges. This shape causes light rays to spread out or diverge after passing through the lens, which results in the formation of a virtual image that is smaller and upright compared to the object.

- A.
  
  Lens
- B.
  
  Cornea
- C.
  
  Retina
- D.
  
  Pupil
Correct Answer
B. Cornea

Explanation
The clear part of the eye that is attached to the sclera is called the cornea. The cornea is a transparent dome-shaped tissue that covers the front part of the eye. It plays a crucial role in focusing light onto the retina, which enables us to see clearly. The cornea also protects the eye from dust, debris, and harmful UV rays. It is responsible for approximately 65-75% of the eye's focusing power.

Which technology relies on mirrors or lenses for an image to be produced?
- A.
  
  Telescope
- B.
  
  Microscope
- C.
  
  Camera
- D.
  
  All of them do
Correct Answer
D. All of them do

Explanation
All of the given options rely on mirrors or lenses for an image to be produced. A telescope uses lenses or mirrors to gather and focus light from distant objects, allowing us to see them more clearly. Similarly, a microscope uses lenses to magnify small objects that are not visible to the naked eye. A camera also uses lenses to focus light onto a photosensitive surface, capturing an image. Therefore, all three technologies rely on mirrors or lenses for image production.

Sound needs ___________ to vibrate to transmit the wave.
- A.
  
  A medium
- B.
  
  Energy
- C.
  
  Gas
- D.
  
  Liquid
Correct Answer
A. A medium

Explanation
Sound is a mechanical wave that requires a medium to travel through. In order for sound to propagate, it needs particles to vibrate and transmit the wave. These particles can be found in solids, liquids, or gases. Therefore, the correct answer is a medium.
