1.Light from space continuously reaches the earth. Let's take a look at the various forms of light arriving from space, including the sunlight that blesses our planet.
Space is filled with waves of various wavelengths. In addition to visible light, there are wavelengths that cannot be seen by the naked eye, such as radio waves and infrared, ultraviolet, X-, and gamma rays. These are collectively known as electromagnetic waves because they pass through space by alternately oscillating between electric and magnetic fields. Light is a type of electromagnetic wave. The electromagnetic waves reaching us consist of only a portion of the visible light, near-infrared rays and radio waves from space because the earth is surrounded by a layer of gases known as the atmosphere. This structure is intimately related to the existence of life on earth.
