Waves: Wavelength, Frequency, and Amplitude

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What is wavelength?

Back

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

Front

What is frequency?

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 wave's energy.

Front

How is amplitude represented in wave equations?

Back

Amplitude is often represented by the letter 'A' in wave equations.

Front

What happens to frequency as energy in a wave increases?

Back

As energy in a wave increases, the frequency increases.

Front

What happens to amplitude as energy in a wave increases?

Back

As energy in a wave increases, the amplitude increases.

Front

What is the relationship between wavelength and frequency?

Back

Wavelength and frequency are inversely related; as one increases, the other decreases.

Front

What is the formula for wave speed?

Back

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

Front

If a wave has a frequency of 4 Hz and a wavelength of 2 meters, what is its speed?

Back

The speed of the wave is 8 meters per second (v = 4 Hz × 2 m).
