Unit 3 Review

Front

What is the definition of frequency in the context of waves?

Back

Frequency is the number of waves that pass a given point every second.

Front

What happens to the frequency of a wave when its wavelength decreases?

Back

The frequency increases.

Front

What is an example of a radio wave application?

Back

Television broadcasting is an example of radio waves.

Front

What type of electromagnetic wave do polarized sunglasses primarily filter?

Back

Polarized sunglasses primarily filter visible light.

Front

What do the terms amplitude, wavelength, and frequency refer to in wave physics?

Back

Amplitude refers to the height of the wave, wavelength is the distance between successive crests, and frequency is the number of waves passing a point per second.

Front

How are amplitude and energy related in waves?

Back

Higher amplitude waves carry more energy.

Front

What is the relationship between wavelength and frequency in electromagnetic waves?

Back

Wavelength and frequency are inversely related; as one increases, the other 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 (or about 186,282 miles per second).

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, from radio waves to gamma rays.

Front

What is the difference between transverse and longitudinal waves?

Back

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