Front

What is frequency?

Back

The number of peaks or valleys in one second.

Front

What does wavelength refer to in a wave?

Back

The distance between two consecutive peaks or valleys.

Front

Define amplitude in the context of waves.

Back

The distance from the starting position to a peak or valley.

Front

What is a peak in a wave?

Back

The highest point of a wave.

Front

What happens to frequency when amplitude increases?

Back

It stays the same.

Front

What is the relationship between wavelength and frequency?

Back

As wavelength increases, frequency decreases.

Front

What is a wave?

Back

A disturbance that transfers energy from one place to another.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.

Front

What is a trough in a wave?

Back

The lowest point of a wave.

Front

How do you measure frequency?

Back

By counting the number of waves that pass a point in one second.
