What is a trough in a wave?

Back

A trough is the lowest point of a wave below the line of origin.

How is pitch defined in terms of sound waves?

Back

Pitch is a measure of how high or low a sound is, determined by the frequency of the sound wave.

What is the line of origin in wave terminology?

Back

The line of origin is the baseline level from which the wave oscillates, typically representing a state of rest.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as the frequency of a wave increases, its wavelength decreases.

What is amplitude in the context of waves?

Back

Amplitude is the maximum displacement of points on a wave from the line of origin, indicating the wave's energy.

Front

What is the formula for wave speed?

Back

Wave speed (v) is calculated using the formula v = frequency (f) × wavelength (λ).

What is the difference between mechanical and electromagnetic waves?

Back

Mechanical waves require a medium to travel through, while electromagnetic waves can travel through a vacuum.

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.
