Light And Sound Energy Quiz Questions!
The sound is as a result of vibrations through the air and cannot pass through a vacuum. Both light and sounds are forms of energy which we learned this past week. Just how much of the topic did you get to understand? Do you know how the two forms of energy travel? Take up the test below and get to understand the topic much better.

When light bounces off a smooth, shiny surface, what process has occurred?
- A.
Refraction
- B.
Reflection
- C.
Transmission
- D.
Photosynthesis
Correct Answer
B. ReflectionExplanation
When light bounces off a smooth, shiny surface, it undergoes the process of reflection. Reflection occurs when light waves strike a surface and bounce back, without being absorbed or transmitted through the material. This process is responsible for our ability to see objects, as the reflected light enters our eyes and forms an image.Rate this question:

Why does blowing into a trumpet make sound?
- A.
The trumpet heats the air
- B.
The trumpet reflects the air
- C.
The air in the trumpet is cooled
- D.
The trumplet causes the air to vibrate
Correct Answer
D. The trumplet causes the air to vibrateExplanation
When air is blown into a trumpet, it passes through the narrow opening of the trumpet's mouthpiece. This causes the air to accelerate and create a fast-moving stream of air. As the fast-moving air hits the back of the trumpet's cup-shaped mouthpiece, it causes the air inside the trumpet to vibrate. These vibrations travel through the trumpet's tubing and are amplified, producing sound. Therefore, the correct answer is that the trumpet causes the air to vibrate.Rate this question:

A road often has reflectors in the middle to help people see the center line. How does the reflectors work?
- A.
It refracts light rays
- B.
It bounces light back
- C.
It absorbs light shined on it
- D.
It makes light with electricity
Correct Answer
B. It bounces light backExplanation
Reflectors on the road work by bouncing back light. When a car's headlights or any other source of light shines on the reflector, it reflects the light back towards the source. This helps drivers to see the center line of the road more clearly, especially at night or in low visibility conditions. By reflecting the light, the reflectors enhance visibility and improve safety on the road.Rate this question:

Which of the following would reflect light rather than refract light?
- A.
A small lens
- B.
A shiny mirror
- C.
A dull black paper
- D.
A magnifying glass
Correct Answer
B. A shiny mirrorExplanation
A shiny mirror would reflect light rather than refract it because of its smooth and polished surface. When light hits the mirror, it bounces off at the same angle, resulting in reflection. Refraction, on the other hand, occurs when light passes through a medium and changes direction. The other options, such as a small lens, a dull black paper, and a magnifying glass, may refract light to some extent due to their material properties or shape.Rate this question:

A student is playing a guitar. Some of the strings vibrate more quickly than other strings. What effect does this have on the sound?
- A.
The faster vibrating strings make louder sounds
- B.
The faster vibrating strings make lower sounds
- C.
The faster vibrating strings make softer sounds
- D.
The faster vibrating strings make higher sounds
Correct Answer
D. The faster vibrating strings make higher soundsExplanation
When the strings of a guitar vibrate more quickly, it means that they have a higher frequency. In terms of sound, higher frequency vibrations result in higher pitched sounds. Therefore, the correct answer is that the faster vibrating strings make higher sounds.Rate this question:
