Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points in phase on a wave, such as from crest to crest or compression to compression.

Front

How is wavelength measured?

Back

Wavelength is measured in meters.

Front

What happens to a wave when it passes from one medium to another?

Back

The speed of the wave may change.

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another due to a change in speed.

Front

What is reflection?

Back

Reflection is the bouncing back of a wave when it meets a surface or object that does not absorb the entire wave’s energy.

Front

What is absorption in wave behavior?

Back

Absorption is the process by which a wave's energy is taken in by a material, reducing the energy of the wave.

Front

What is transmission in wave behavior?

Back

Transmission is the passing of a wave through a medium without being absorbed.

Front

What is the relationship between frequency and wavelength?

Back

Frequency and wavelength are inversely related; as frequency increases, wavelength decreases.

Front

What is the formula for wave speed?

Back

Wave speed = frequency × wavelength.

Front

What are the units of frequency?

Back

Frequency is measured in Hertz (Hz).
