Which describes a property shared by ultraviolet light and X-rays?

A They are both transverse waves.

B They share the same wavelength.

C They contain less energy than visible light.

D They both require a medium to travel through.

A They are both transverse waves.

Explanation:

Both of them are non mechanical transverse wave. In transverse wave the movement in the medium particle is perpendicular to the direction of propagation of wave. I electromagnetic wave, the fluctuation is in electric and magnetic field which contains the energy of wave. The direction of their fluctuation is perpendicular to the direction of propagation of wave.

B is wrong as X - rays have smaller wave length.

The energy of both the rays is more than that of visible light.

They do not require medium to travel.
