Questions and Answers

1.

Choose the best answerLight can travel in __________________________.
- A.
  
  Bulbs
- B.
  
  Wires
- C.
  
  Straight lines
- D.
  
  Cardboard boxes
Correct Answer
C. Straight lines

Explanation
Light can travel in straight lines because it is a form of electromagnetic radiation that moves in a straight path until it encounters an obstacle or is redirected by a reflective surface. This property allows light to travel through a vacuum or transparent mediums such as air, water, or glass without deviating from its original path.

Light can travel through ______________________.
- A.
  
  Opaque objects.
- B.
  
  Metal objects
- C.
  
  Soft objects
- D.
  
  Transparent objects
Correct Answer
D. Transparent objects

Explanation
Light can travel through transparent objects because they allow light to pass through them without scattering or absorbing it. Transparent objects have a molecular structure that allows light to pass through, making them see-through or clear. Opaque objects, on the other hand, do not allow light to pass through them, while metal objects and soft objects may partially block or absorb light depending on their properties.

Fill in the missing wordWhen light travels around corners it is because it __________________ off an object.
- A.
  
  Refracts
- B.
  
  Reflects
- C.
  
  Absorbs
- D.
  
  Bends
Correct Answer
B. Reflects

Explanation
When light travels around corners, it is because it reflects off an object. Reflection occurs when light bounces off the surface of an object and changes direction. This phenomenon allows light to change its path and continue traveling in a different direction, enabling it to reach areas that are not directly in its line of sight.

  Positive
Correct Answer(s)
A. Fluoresent
B. Incandesent
D. Led

Explanation
The correct answer includes the types of lights that are commonly used: fluorescent, incandescent, and LED lights. These three types of lights have different characteristics and are used for various purposes. Fluorescent lights are known for their energy efficiency and are commonly used in commercial buildings. Incandescent lights produce light by heating a filament and are often used in residential settings. LED lights are highly energy-efficient and have a longer lifespan, making them popular for both residential and commercial applications.

If I had a completely dark room and I held up a bright yellow highlighter I would be able to see it.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
In a completely dark room, there would be no light available to reflect off the bright yellow highlighter. Therefore, even if the highlighter is held up, it would not be visible to the human eye. Hence, the statement is false.

- D.
  
  The boy will need a torch or candle to be able to see anything.
- E.
  
  When the room is dark the boy will still cast a shadow.
- F.
  
  If there was an owl in the room the boy will only be able to see the owl’s eyes because its eyes will shine in the dark.
Correct Answer(s)
A. It will be dark in the room and the boy won’t be able to see the anything.
D. The boy will need a torch or candle to be able to see anything.

Explanation
When a boy switches a light off in a room with no windows, it will be dark in the room and the boy won't be able to see anything. Additionally, the boy will need a torch or candle to be able to see anything.

Materials that block out light are ________________.

Correct Answer(s)
opaque

Explanation
Opaque materials are those that do not allow light to pass through them. They are not transparent or translucent, but instead block out light completely. Therefore, the correct answer for this question is "opaque".

9.

Materials that allow light to pass through them are _________________________.

Correct Answer(s)
transparent, transperent

Explanation
Transparent materials are those that allow light to pass through them without scattering or diffusing it. These materials have a clear and unobstructed view, enabling objects on the other side to be seen clearly. They have a high transmission of light, making them ideal for applications such as windows, lenses, and optical devices. "Transperent" is likely a misspelling of "transparent" and has the same meaning in this context.

Tick all the correct answers.The shape of a shadow is affected by:
- A.
  
  How big the light is and what colour it is.
- B.
  
  How strong the light is and the type of bulb.
- C.
  
  The shape of the object blocking the light
- D.
  
  How close the object is to the light source
- E.
  
  The position of the light source relative to the object, for example, whether it is above or at the same level as the object.
Correct Answer(s)
C. The shape of the object blocking the light
D. How close the object is to the light source
E. The position of the light source relative to the object, for example, whether it is above or at the same level as the object.

Explanation
The shape of a shadow is affected by the shape of the object blocking the light because the shadow will take on the same shape as the object. The proximity of the object to the light source also affects the shape of the shadow, as a closer object will create a larger and more defined shadow. Additionally, the position of the light source relative to the object plays a role in the shape of the shadow, as the angle and direction of the light will determine the shape and orientation of the shadow.

The earth's most important light source is the _________.

Correct Answer(s)
sun

Explanation
The sun is the earth's most important light source because it emits light and heat energy, which is essential for sustaining life on our planet. The sun's rays provide light for photosynthesis, allowing plants to grow and produce oxygen. It also provides warmth, regulating the earth's temperature and creating different climates. Additionally, sunlight is crucial for our daily activities, as it enables us to see and navigate our surroundings. Without the sun, life on earth would not be possible.
