Waves Assessment 1 Review

Front

What is a wave?

Back

A wave is a disturbance that transfers energy through space or matter, typically characterized by its amplitude, frequency, and wavelength.

Front

What is frequency in the context of waves?

Back

Frequency is the number of waves that pass a given point in one second, measured in Hertz (Hz).

Front

What is amplitude?

Back

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

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points that are in phase on a wave, such as crest to crest or trough to trough.

Front

What happens to the frequency of a wave if the wavelength increases?

Back

If the wavelength increases, the frequency decreases, assuming the speed of the wave remains constant.

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another, caused by a change in speed.

Front

Which color of light refracts the most when passing through a prism?

Back

Violet light refracts the most because it has the highest frequency and shortest wavelength.

Front

What is the Doppler effect?

Back

The Doppler effect is the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

Front

What is the relationship between pitch and frequency?

Back

Pitch is the perceived frequency of a sound; higher frequencies correspond to higher pitches.

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).
