What is a trough in wave properties?

Back

A trough is the lowest point in a wave, where the wave's displacement is at its minimum.

Front

What happens to the frequency of electromagnetic waves as the distance between the source and the observer decreases?

Back

The frequency of the waves increases as the distance decreases, indicating that the source is moving closer.

Front

If a sound wave has a wavelength of 2.0 meters, what is the distance between the center of a compression and the center of an adjacent rarefaction?

Back

1.0 meter.

Front

What does a diagram of circular waves created at various times illustrate?

Back

It illustrates the Doppler effect, which describes the change in frequency or wavelength of a wave in relation to an observer moving relative to the wave source.

Front

How far away will you see yourself in a mirror if you stand 0.75 meters in front of it?

Back

You will see yourself 1.5 meters away, as the distance to the mirror is equal to the distance back.

Front

Define wavelength in the context of wave properties.

Back

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

Front

What is the relationship between frequency and wavelength in a wave?

Back

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

Front

What is the principle of superposition in wave interference?

Back

The principle of superposition states that when two or more waves overlap, the resulting wave displacement is the sum of the individual displacements.

Front

What is refraction in wave properties?

Back

Refraction is the bending of waves as they pass from one medium to another, caused by a change in speed.

Front

Explain the concept of resonance in wave phenomena.

Back

Resonance occurs when an object is forced to vibrate at its natural frequency, resulting in a significant increase in amplitude.
