Wave Study Guide

Front

What is the formula to calculate the speed of a wave?

Back

Speed = Wavelength × Frequency

Front

What happens to the frequency of a wave if the speed increases but the wavelength remains the same?

Back

The frequency increases.

Front

What is wavelength?

Back

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

Front

What is frequency?

Back

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

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum height of a wave from its rest position.

Front

How does the medium affect wave speed?

Back

The type of medium (solid, liquid, gas) affects how fast a wave travels through it.

Front

What happens to the wavelength as you move from radio waves to gamma rays?

Back

The wavelength decreases.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as one increases, the other decreases.

Front

What is the unit of measurement for frequency?

Back

Hertz (Hz) is the unit of measurement for frequency.

Front

If a wave has a frequency of 10 Hz and a wavelength of 2 meters, what is its speed?

Back

Speed = Wavelength × Frequency = 2 m × 10 Hz = 20 m/s.
