Unit 5 Review - Waves

Front

What happens to the loudness of a sound wave when its amplitude increases?

Back

The sound wave becomes louder.

Front

In which medium do light waves travel the fastest?

Back

Light waves travel fastest in empty space.

Front

What is the reason a glass prism can bend light?

Back

Light is refracted as it enters a different medium.

Front

How many wavelengths are present in a given wave diagram if there are 3 complete cycles?

Back

There are 3 wavelengths.

Front

What type of wave is a sound wave classified as?

Back

A sound wave is an example of a compressional wave.

Front

Define wavelength in the context of waves.

Back

Wavelength is the distance between two consecutive points in phase on a wave, such as crest to crest.

Front

What is the relationship between frequency and wavelength in waves?

Back

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

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another due to a change in speed.

Front

What is the difference between transverse and compressional waves?

Back

Transverse waves oscillate perpendicular to the direction of wave travel, while compressional waves oscillate parallel to the direction of wave travel.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature is approximately 343 meters per second.
