Unit 4 Test Review: Waves

Front

What happens when you see the color black?

Back

All colors are absorbed.

Front

How does sound travel through different materials?

Back

Sound travels slower through materials that are less dense, such as air.

Front

What is reflection in terms of waves?

Back

Reflection is when a wave bounces off a surface.

Front

What characteristics define a loud and high-pitched sound?

Back

A sound that is loud and has a high pitch is represented by wave A.

Front

What do all waves in the electromagnetic spectrum have in common?

Back

All waves in the electromagnetic spectrum have the same speed.

Front

Define wavelength in the context of waves.

Back

Wavelength is the distance between successive crests of a wave.

Front

What is the difference between transverse and longitudinal waves?

Back

Transverse waves move perpendicular to the direction of the wave, while longitudinal waves move parallel.

Front

What is amplitude in a wave?

Back

Amplitude is the height of the wave from its rest position, indicating the energy of the wave.

Front

How does density affect the speed of sound?

Back

Sound travels faster in denser materials compared to less dense materials.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation.
