Which type of radiations are absorbed by the upper layer of the atmosphere? A. Radio-waves B. Infrared C. Visible D. Ultraviolet

The correct answer is D. Ultraviolet.

Ultraviolet radiation is a type of electromagnetic radiation with wavelengths shorter than visible light. It is absorbed by the upper layer of the atmosphere, called the ozone layer. The ozone layer protects life on Earth by absorbing most of the Sun’s harmful ultraviolet radiation.

Radio waves are a type of electromagnetic radiation with wavelengths longer than visible light. They are not absorbed by the upper layer of the atmosphere and can travel through space.

Infrared radiation is a type of electromagnetic radiation with wavelengths longer than visible light but shorter than radio waves. It is absorbed by the Earth’s atmosphere and is responsible for the greenhouse effect.

Visible light is a type of electromagnetic radiation with
