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.

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.

explanation:

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
