Answer:
The amount of energy of a wave can be determined by measuring its wavelength, the distance between consecutive points of a wave.
Visible light is a type of radiant energy within the electromagnetic spectrum; other types of electromagnetic radiation include UV, infrared, gamma, and radio rays as well as X-rays.
The difference between wavelengths relates to the amount of energy carried by them; short, tight waves carry more energy than long, wide waves.
Stars Like the Sun. When the core runs out of hydrogen fuel, it will contract under the weight of gravity. ... The upper layers will expand and eject material that will collect around the dying star to form a planetary nebula. Finally, the core will cool into a white dwarf and then eventually into a black dwarf.
