http://performativedesign.com/definitions/light/reflectance/ Webin astronomy, backscattered light is that which is reflected with a phase angle of less than 90°. In other cases, the scattering intensity is enhanced in backward direction. This can have different reasons: In alpenglow, red light prevails because the blue part of the spectrum is depleted by Rayleigh scattering.

What determines how much light is reflected and refracted?

WebJan 8, 2024 · Meaning if you shine a light at a mirror at the critical angle, it will travel at 100% lumosity. But each angle you move afterwards will gradually sink the lights power as it bounces, and more passes it through at the refraction angle. But do not forget your heat index as it reflects.
