Unit 1 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 crests or troughs in a wave.

Front

What is amplitude?

Back

Amplitude is the maximum distance from the rest position to the crest or trough of a wave.

Front

What is the medium in wave propagation?

Back

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

Front

What type of wave requires a medium to travel?

Back

Mechanical waves require a medium to travel.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, the particle movement is perpendicular to the direction of wave travel, while in longitudinal waves, the particle movement is parallel to the direction of wave travel.

Front

What is an example of a transverse wave?

Back

An example of a transverse wave is a wave on a string or electromagnetic waves.

Front

What is an example of a longitudinal wave?

Back

An example of a longitudinal wave is a sound wave.

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 wavelength and frequency?

Back

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