Waves

Front

What is Amplitude?

Back

Amplitude is the maximum distance that the particles of a wave move from their rest position. It is a measure of the energy of the wave.

Front

What happens to the frequency of a wave when energy is increased?

Back

Increasing the energy put into a wave increases its frequency.

Front

Why was the experiment to time light between two lighthouses unsuccessful?

Back

The experiment failed because light travels too fast for a clock to measure in a short distance.

Front

What medium do light waves pass through?

Back

Light waves can pass through a vacuum, as well as solids and fluids.

Front

What are Transverse Waves?

Back

Transverse waves are waves in which the particles of the medium move perpendicularly to the direction of the wave.

Front

What is Wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is a Crest in a wave?

Back

A crest is the highest point of a wave.

Front

What is a Trough in a wave?

Back

A trough is the lowest point of a wave.

Front

What are Longitudinal Waves?

Back

Longitudinal waves are waves in which the particles of the medium move parallel to the direction of the wave.

Front

What is the relationship between wave speed, frequency, and wavelength?

Back

Wave speed = frequency × wavelength.
