Atmosphere refers to the thin blanket of air that surrounds the earth.
It serves many important functions such as:
- It contains a mixture of gases that are essential for the existence of life on earth. For example, carbon dioxide is essential for photosynthesis and oxygen is essential for cellular respiration.
- It also serves as the reservoir of water in the form of water vapor. Thus, it forms an important constituent for the water cycle.
- It maintains the temperature of the earth. Through the greenhouse effect, it maintains the temperature of the earth in limited ranges.
- It protects the earth from harmful rays of the sun. For example, ozone inhibits the entry of most of the UV rays of the sun into the earth environment.
As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter.
