1) Visible light is absorbed by plants to supply energy for growth. 2) Visible light is used to measure the distance to distant stars. 3) Visible light hitting photovoltaic solar cells generates electricity. 4) Visible light stimulates the production of specific hormones in the human body to help set your internal circadian rhythms.
