4 days ago · Sunlight, solar radiation that is visible at Earth’s surface. The amount of sunlight is dependent on the extent of the daytime cloud cover. Some places on Earth receive more than 4,000 hours per year of sunlight, as in the Sahara; others receive less than 2,000, as in regions of frequent storminess.

Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere as daylight when the Sun is above the horizon.
Sunlight travels as waves of energy, and different colors of light have different wavelengths. Red light has long wavelengths, while blue light has short wavelengths. Light bounces off of air molecules in the Earth's atmosphere, scattering in all directions.
When the sun’s rays enter the earth, they get distorted by the earth’s atmosphere, air molecules, dust, smoke and pollution. We know that different colours of the spectrum have different wavelengths.
Sunlight, also known as solar radiation, refers to the incoming light to the Earth that originated from the Sun. This light represents a portion of the electromagnetic spectrum that includes infrared, visible light, and ultraviolet light.
May 29, 2023 · Sunlight refers to the electromagnetic radiation of the sun that reaches the earth, particularly infrared, visible light, and ultraviolet light. The electromagnetic radiation consists of electromagnetic waves that can be characterized by frequency or wavelength of oscillations.
Oct 27, 2022 · For 4.5 billion years, the Sun has generated energy to power the solar system. Visible light is the most obvious form of that energy. Every day the Earth turns, and the new day starts with sunlight. Here on Earth, the Sun’s light causes day and night, shadows, eclipses, and seasons.
