Question

What is the difference between TIR & normal reflection?

• A. TIR, unlike reflection, occurs when light moves from rarer to denser medium only however the image formed in TIR is comparatively dimmer
• B. TIR, unlike reflection, occurs when light moves from rarer to denser medium only however the image formed in TIR is comparatively brighter
• C. TIR, unlike reflection, occurs when light moves from denser to rarer medium only however the image formed in TIR is comparatively dimmer
• D. TIR, unlike reflection, occurs when light moves from denser to rarer medium only however the image formed in TIR is comparatively brighter
• E. TIR, unlike reflection, occurs when light moves from rarer to denser medium only however the image formed in TIR has same brightness as that by reflection

Answer 1

The correct option is D

TIR, unlike reflection, occurs when light moves from denser to rarer medium only however the image formed in TIR is comparatively brighter

TIR only occurs when light is moving from Denser to Rarer medium. TIR only occurs when angle of incidence of light is greater than critical angle images formed by TIR ARE brighter as during TIR no light is absorbed.
