Light

Light can travel in straight lines and doesn't need a substance to travel through it. Light is made of all the colours such as: Red, orange, yellow, green, blue, indigo and violet. You can break up the light by using a glass prism.

Light is measured in wave lengths on an electromagnetic spectrum. Light exists in two very different forms at the same time. One form is tiny particles called photons. These photons carry a fixed amount of energy but have no mass. Photons are massless, so they always move at the speed of light in a vacuum.

Light or visible light is electromagnetic radiation that can be perceived by the human eye
