The energy coming from the sun to the earth's surface is called solar energy. most of it is in the form of electromagnetic radiation from the visible wavelengths. another wavelength that reaches earth's surface is responsible for sunburn, skin cancer, and is the reason why we wear cool sunglasses. what is this type of electromagnetic radiation? a) infrared b) microwave c) ultraviolet d) visible

The correct option is (C).

Explanation:

The energy coming from the sun to the Earth's surface is called solar energy.

Ozone layer prevents the harmful radiation from entering the earth's surface.  Due to the depletion in the ozone layer, some harmful radiation comes on the earth's surface.

Ultraviolet radiation is an electromagnetic wave. It is very harmful radiation. It can cause skin cancer and sun burn. This is the reason why we wear sunglasses to protect our eyes from UV rays.

Therefore, the correct answer is ultraviolet.  

wavelength divides in half and speed stays the same.
