7.2 The spectrum of the sun Visible light and infrared radiation constitute the major fraction of solar radiation reaching the atmosphere of the Earth (Fig. 7-1). Approximately 40 % of the radiation energy is visible light of wavelengths between 400 and 700 nm.. Visible Light and UV Radiation 75 Effects of the ozone layer Ozone, O 3, is produced when oxygen, O 2, in the upper atmosphere absorbs UVC (Î»). This absorption completely eliminates UVC from the solar radiation and dissociates oxygen molecules to oxygen atoms.
Radiation from the Sun, which is more popularly known as sunlight, is a mixture of electromagnetic waves ranging from infrared (IR) to ultraviolet rays (UV).It of course includes visible light, which is in between IR and UV in the electromagnetic spectrum. Extreme Ultraviolet Sun.ow, since the average distance between the Earth and the Sun over one Earth orbit is one AU (about 150,000,000,000 m), then it will take about 8 minutes for radiation from the Sun to get to Earth. Actually, the Sun does not only produce IR, visible light, and UV.
