Which type of electromagnetic wave is used for warming, photosynthesis in plants, and making vitamin d in humans? uv wave radio wave visible light wave gamma ray

UV wave

Explanation:

Ultraviolet light (UV light), whose wavelength is approximately between 100 nm and 380 nm; is a type of electromagnetic radiation that is not visible to the human eye.

This type of radiation is an important factor in the photosynthesis process, in which the Ultraviolet light is transformed into stable chemical energy, converting inorganic matter into organic matter.  This process is carried out by living beings that are mostly made up of chlorophyll (a green pigment), such as plants and algae.

In addition, UV light is important in making vitamin D in humans, becausa this vitamin is synthesized by the skin from cholesterol, through a chemical reaction that needs short-wave ultraviolet rays (also called UVB).
