Helps plants grow: The Sun is highly important for plants, as it helps trigger photosynthesis. When the Sun beams down on plants, the solar energy causes a chemical reaction in plant cells. This chemical reaction gives plants energy to produce sugar and oxygen. They consume the sugar, which helps them grow, and emit oxygen into the air for us ...
The visible band of the EM spectrum is visible to us because our eyes and brain can perceive this band of electromagnetic wavelengths. State two reasons why the sun appears somewhat yellow to us. The sun appears slightly yellow to us because its most intense emissions are in the yellow band, and our eyes and brain are most sensitive to the ...
