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, such as crest to crest or trough to trough.

Front

What is amplitude?

Back

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

Front

What is the speed of a wave?

Back

The speed of a wave (v) is the distance traveled by a wave in a given amount of time, often calculated using the formula v = fλ, where f is frequency and λ is wavelength.

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 the relationship between speed, wavelength, and frequency?

Back

The relationship is given by the equation v = fλ, where v is speed, f is frequency, and λ is wavelength.

Front

What are transverse waves?

Back

Transverse waves are waves in which the particle displacement is perpendicular to the direction of wave propagation, such as light waves and waves on a string.

Front

What are longitudinal waves?

Back

Longitudinal waves are waves in which the particle displacement is parallel to the direction of wave propagation, such as sound waves.

Front

What are nodes and antinodes in a standing wave?

Back

Nodes are points of no displacement in a standing wave, while antinodes are points of maximum displacement.

Front

What is constructive interference?

Back

Constructive interference occurs when two waves meet in phase, resulting in a wave of greater amplitude.
