Question

Compare and contrast visible light and ultra violet rays coming from the sun. A) Ultraviolet waves are energy waves and light is not. B) Light are energy waves and ultraviolet rays are not. C) Both are waves of energy, but ultraviolet waves cannot be seen. D) Both are waves of energy, but visible light waves are more dangerous.

Answer 1

Answer:

C) Both are waves of energy, but ultraviolet waves cannot be seen.

Explanation:

Both visible light and ultraviolet are two manifestations of the same thing: electromagnetic radiation (which is, basically, energy in one of its forms). They both travel empty space as waves, but visible light has a longer wavelength, which means that the distance between succesive peaks of the wave is larger than that of ultraviolet radiation. Visible light just happens to have a wavelength in the range our eyes are capable of seeing, but ultraviolet has a shorter wavelength than that, therefore we cannot see it.
