Waves Test Review

Front

What is refraction?

Back

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

Front

What causes refraction?

Back

Refraction occurs due to the change in speed of light as it passes between different mediums.

Front

What is reflection?

Back

Reflection is the bouncing back of a wave when it meets a surface or boundary that does not absorb the entire wave’s energy.

Front

How are amplitude, volume, and energy related in sound waves?

Back

Higher amplitude increases volume and energy in a sound wave.

Front

What are radio waves used for?

Back

Radio waves are used in AM/FM radio broadcasting and mobile phone communication.

Front

What are infrared waves used for?

Back

Infrared waves are used in remote controls for TVs, thermal imaging cameras, and infrared communication systems.

Front

Define wavelength.

Back

Wavelength is the distance between successive crests of a wave, typically measured in meters.

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 (km/s).

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles and openings.
