Why does the phenonmenon of total internal reflection find important application in periscope and binoculer .....plz answer fast today is exam..
Answers
because it does not absorbs any energy and gives a clear view, it doesn't get Detoriates
Therefore total reflection mirror find importance in periscope and binoculars
complete reflection of a ray of light within a medium such as water or glass from the surrounding surfaces back into the medium. The phenomenon occurs if the angle of incidence is greater than a certain limiting angle, called the critical angle.
total internal reflection takes place at the boundary between two transparent media when a ray of light in a medium of higher index of refraction approaches the other medium at an angle of incidence greater than the critical angle.
Glass prisms can be shaped to produce total internal reflection and as such are employed in binoculars, periscopes, telescopes, and other optical instruments.
Hope It helps you
