Light & Sound Waves

Front

What happens to a light ray when it strikes an object?

Back

The light ray is reflected.

Front

Through which material does sound travel fastest?

Back

Sound travels fastest through metal.

Front

What do all waves carry as they travel from one place to another?

Back

All waves carry energy.

Front

Define reflection in simple terms.

Back

Reflection is when light bounces off an object.

Front

What is the term for any substance that sound can travel through?

Back

The term is 'Medium'.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light, while refraction is the bending of light as it passes through different mediums.

Front

What is the speed of sound in air compared to that in water?

Back

Sound travels faster in water than in air.

Front

What is the relationship between wavelength and frequency in waves?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What is the principle of superposition in wave theory?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave is the sum of the individual waves.

Front

How does temperature affect the speed of sound in a medium?

Back

The speed of sound increases with an increase in temperature.
