Difference between internal reflection and total internal reflection
-Reflection and total internal reflection are physical properties of waves. Reflection occurs in all kind of waves like sound, water etc. but total internal reflection occurs only with light rays.
· Total internal reflection occurs when light passes through denser medium to the lighter medium. But for reflection there is no such restriction to consider.
· In reflection of a wave, both reflection and refraction (passing through second medium) waves occur. But in total internal reflection, only reflection ray is occurs no refraction is allowed.
· In total internal reflection, energy of incident ray and reflected ray are equal. However, in reflection it does not.
