Range the electromagnetic waves from shortest wavelength to longest wavelength- | 1-Gamma rays 2-X-Rays 3-Ultraviolet 4-Visible light 5-Infrared 6-Radio |
True or false - The wave with the highest frequency and shortest wavelength has the greater amount of energy | True |
Gamma rays to radio waves are all types of ___________ | Electromagnetic radiation |
What is thermal radiation? | Energy that an opaque object, like a planet, produce based on its temperature. |
What is a Stefan-Boltzmann law? | A law which stated that the higher the energy, the more radiation a star gives off at any wavelength |
What is Wein's Law? | The closer the star is to blue, the hotter, thus higher energy. |
According to Wein's Law, how hot is the red temperature? | Cooler |
According to Stefan-Boltzmann law, why doesn't the object emit much radiation? | The object doesn't have the highest energy. |
