Waves Review

Front

What is the definition of wavelength?

Back

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

Front

What does frequency measure in a wave?

Back

Frequency measures the number of waves that pass a given point in one second, typically expressed in hertz (Hz).

Front

What is the Doppler Effect?

Back

The Doppler Effect is the apparent change in pitch of a sound due to the relative motion between the observer and the source of the sound.

Front

What is amplitude in the context of waves?

Back

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

Front

What is a medium in wave terminology?

Back

A medium is any substance through which a wave travels, such as air, water, or solid materials.

Front

What is the relationship between wavelength and frequency?

Back

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

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave, representing the maximum displacement above the rest position.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave, representing the maximum displacement below the rest position.

Front

How does sound travel through different media?

Back

Sound travels faster in solids than in liquids, and faster in liquids than in gases due to the density and elasticity of the medium.

Front

What is the formula for calculating wave speed?

Back

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