... Refraction is the bending of light as a result of it passing from one medium (such as air) to another (such as glass). A refracting telescope makes use of this property by using a lens with curved surfaces. As light goes from air to glass and then back to air, its path is deviated toward the optical ...

It does not, however, necessarily need to have a higher luminosity, L = 4πR2 σT 4 , because while luminosity is dependent on temperature, it is also dependent on the size of the blackbody. Thus, without ...
