There are two windows located in the visible and radio wave bands of the electromagnetic spectrum. O b. There is one window located in the visible band of the electromagnetic spectrum. O c. There are three windows located in the ultraviolet, visible, and radio wave bands of the electromagnetic spectrum. O d. There is one window located in the microwave band of the electromagnetic spectrum

Explanation / Answer

Because of the presence of ozone, water vapour, carbon-dioxide and other molecules in the atmosphere most of the electromagnetic waves are absorbed in the upper atmosphere and we see specific portions of the electromagnetic spectrum. This phenomena is called atmospheric window.
