What does UV stand for in terms of electromagnetic waves?

Back

UV stands for Ultraviolet, which are electromagnetic waves of frequencies higher than those of violet light.

Front

What is a vacuum?

Back

A vacuum is an empty space with no particles and no pressure.

Front

What is a transverse wave?

Back

A transverse wave is a type of wave where the disturbance moves perpendicular to the direction of the wave.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave where the disturbance moves parallel to the direction of the wave.

Front

What is wavelength?

Back
