Unit 3 Test/Kahoot Review Waves Properties

Front

What is a mechanical wave?

Back

A mechanical wave is a wave that requires a medium (solid, liquid, or gas) to travel through.

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a wave that does not require a medium and can travel through a vacuum.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum displacement of points on a wave from its rest position, related to the energy of the wave.

Front

How does amplitude affect energy in a wave?

Back

As amplitude increases, the energy of the wave also increases.

Front

What type of wave is used in TV remote controls?

Back

Infrared waves are used in TV remote controls.

Front

Which color of light has the highest frequency?

Back

Green light has a higher frequency than red, yellow, and orange.

Front

What is the relationship between frequency and wavelength?

Back

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

Front

What is the speed of light in a vacuum?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.

Front

What are the two main types of mechanical waves?

Back

The two main types of mechanical waves are transverse waves and longitudinal waves.
