1. Visible Light
-Up to 500 000 wave lengths can fit into 1 cm
-Red has the longest wavelength, lowest frequency and lowest energy
-Violet has the shortest wavelength, highest frequency, and highest energy
-Plants rely on the energy provided by visible light to power their photosynthetic cycle, allowing them to
make simple sugars from components found in their environment. Without light, photosynthetic plants
would exhaust their energy supplies and die
-Besides relying on photosynthetic sources of food, humans also need sunlight to function. According to
Lisa Conti of Scientific American, lack of sunlight can prevent synthesis of neurotransmitters, leading to
depression and brain damage
-Too much light can damage the retina in your eye. This can happen when you look at something very
bright, such as the Sun. Although the damage can heal, if it's too bad it'll be permanent.
