Apolice officer uses a radar gun to determine the speed of a car. a specialized radar gun uses ultraviolet light to determine the speed. what describes the wave used? check all that apply. transverse longitudinal heat electromagnetic sound

transverse

electromagnetic

Explanation:

We have two types of waves:

- Electromagnetic waves: these waves are produced by the oscillations of electric and magnetic field, and they do not a medium to propagate (they can travel through a vacuum)

- Mechanical waves: these waves are produced by the oscillations of the molecules in a medium, so they do need a medium to propagate (an example are sound waves).

Ultraviolet waves are part of the electromagnetic waves.

Moreover, waves can be further classified based on the direction of their oscillations:

- Transverse waves: in these kinds of waves, oscillations occur perpendicularly to the direction of propagation of the wave

- Longitudinal waves: in these kinds of waves, oscillations occur parallel to the direction of propagation of the wave

Electromagnetic waves are always transverse waves, and since ultraviolet are electromagnetic waves, this means that ultraviolet are also transverse waves.
