Waves

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 that are in phase on a wave, typically measured from crest to crest or trough to trough.

Front

What is frequency?

Back

Frequency is the number of complete waves that pass a given point in one second, measured in hertz (Hz).

Front

What is the formula for wave speed?

Back

The formula for wave speed is speed (v) = frequency (f) x wavelength (λ).

Front

What is amplitude?

Back

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

Front

What are radio waves?

Back

Radio waves are electromagnetic waves with the longest wavelengths in the electromagnetic spectrum, used for communication.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet and combine to form a wave with a larger amplitude.

Front

What is destructive interference?

Back

Destructive interference occurs when two waves meet and combine to form a wave with a smaller amplitude.

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 the period of a wave?

Back

The period is the time it takes for one complete wave to pass a given point, measured in seconds.
