Answer 1

Answer:

Light energy is a form of electromagnetic radiation. Light consists of photons, which are produced when an object's atoms heat up. Light travels in waves and is the only form of energy visible to the human Eye.Light energy, like sound energy, travels out in all directions in waves. Examples: A light bulb, the glowing coils on a toaster, the sun, and even headlights on cars.

Light is electromagnetic radiation that has properties of waves. The electromagnetic spectrum can be divided into several bands based on the wavelength. As we have discussed before, visible light represents a narrow group of wavelengths between about 380 nm and 730 nm.
