What is the difference between a red light and green light in the terms of frequency and wavelength

The color red has a higher frequency than the color green. The frequency of the color red is 780nm or 780 nanometers. The frequency of the color green is 560nm (nanometers). So the red lights wave length is shorter than the green wave length. 

Heat is involved in chemical change in two ways; chemical changes either result in heat being added to or removed from an object, and chemical changes require a certain amount of heat before they can take place.
