Unit 5 Practice Test

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another, caused by a change in their speed.

Front

How does the speed of sound vary in different materials?

Back

The speed of sound is higher in solids than in liquids due to the closer packing of atoms in solids.

Front

What type of waves are all the waves in the electromagnetic spectrum?

Back

All waves in the electromagnetic spectrum are transverse waves.

Front

What does it mean for two waves to have the same wavelength but different amplitudes?

Back

Two waves can have the same wavelength but different amplitudes, meaning they oscillate at the same distance but one wave has a greater height than the other.

Front

What happens to wavelength and frequency as we move from red to violet in the visible spectrum?

Back

As we move from red to violet, the wavelength decreases and the frequency increases.

Front

Define amplitude in the context of waves.

Back

Amplitude is the maximum extent of a wave's oscillation, measured from its rest position.

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 a transverse wave?

Back

A transverse wave is a wave in which the oscillation is perpendicular to the direction of the wave's travel.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a wave in which the oscillation is in the same direction as the wave's travel.

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles and openings.
