The sun emits its most intense radiation
ultraviolet light
radio waves
visable light
infrared radiation

The correct answer is Visible light.

Explanation:

The range of wavelength of electromagnetic waves emitted by Sun that reaches Earth lie in three regions: ultraviolet, visible and infrared. This spectrum is known as Solar spectrum.

This spectrum extends from 0.29 µm (or 290 nm) in the longer wavelengths of ultraviolet region to 3.2 µm (3,200 nm) in the far infrared.

The peak wavelength of this spectrum lies in the visible region.

Hence, the correct answer is Visible light.
