The difference between TIR and normal reflection are tabulated below.
|Total Internal Reflection (TIR)||Reflection of light|
|It only happens when light travels from a denser medium to a lighter medium.||When a light ray passes from a lighter medium to a denser medium, it will be reflected.|
|TIR arises only when some conditions are met.||Reflection of light rays occur at any boundary between two optical media.|
|All the light is reflected in total internal reflection.||During normal reflection, only a portion of the total energy in the light is reflected. Parts of it are scattered, while others are refracted.|
|In total internal reflection, the light intensity is higher, and the objects shine brighter than in ordinary reflection. Due to total internal reflection, diamonds sparkle.||The brightness of normal reflection images is less.|
