waves and energy

Front

What is the definition of wavelength?

Back

Wavelength is the distance between successive crests or troughs of a wave.

Front

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

Back

The wavelength decreases.

Front

What is amplitude in the context of waves?

Back

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

Front

Define diffraction in terms of wave behavior.

Back

Diffraction is the bending of waves as they move around obstacles or pass through narrow openings.

Front

What is a standing wave?

Back

A standing wave is a wave that appears to stay in one place and does not seem to move through a medium.

Front

Explain destructive interference.

Back

Destructive interference occurs when two or more waves interact and combine to produce a wave with a smaller displacement.

Front

What is constructive interference?

Back

Constructive interference occurs when two or more waves interact and combine to produce a wave with a larger displacement.

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

Define refraction in the context of waves.

Back

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

Front

What is the relationship between frequency and wavelength?

Back

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