Light and Sound; Test Review

Front

What is refraction of light?

Back

Refraction of light is the bending of light as it passes from one medium to another, causing objects to appear distorted, like a straw appearing bent in a cup.

Front

What type of wave is a sound wave?

Back

A sound wave is a compression wave, which means it travels by compressing and expanding the medium it moves through.

Front

Which material does sound travel through fastest?

Back

Sound travels fastest through solids, such as a metal rod, compared to liquids and gases.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive peaks or troughs in a wave. Longer wavelengths mean lower frequencies.

Front

What is pitch in sound?

Back

Pitch is how high or low a sound is, determined by the frequency of the sound wave. Higher frequency means higher pitch.

Front

What happens to light when it hits a mirror?

Back

When light hits a mirror, it reflects off the surface, allowing us to see our image.

Front

What is the difference between a sound wave and a light wave?

Back

Sound waves are mechanical waves that require a medium to travel through, while light waves are electromagnetic waves that can travel through a vacuum.

Front

How does sound travel through air?

Back

Sound travels through air by causing air molecules to vibrate, creating compressions and rarefactions.

Front

What is an example of refraction in everyday life?

Back

An example of refraction is when you look at a straw in a glass of water and it appears bent.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.
