WebAll of the light incident on the interface is reflected back into the incident medium! The smallest angle of incidence at which total internal reflection occurs is called the critical … WebSnell's law works whether n1>n2 or n2>n1. Working the numbers, you'll see that in your case (the incident side is usually denoted the 'n1' side) that the angle between the normal and …

WebSin α1 / Sin α2 = n2/ n1. Here ‘α1’ measures the angle of incidence ‘α2’ measures the angle of refraction ... This gives the total internal reflection. That means, when light ray travels from lower medium to higher medium, it bends towards the normal with respect to the interface. Websin(criticle angle) = (n2/n1)(sin 90 degrees) = (n2/n1) Where n1 = index of refraction in 1st medium n2 = index of refraction in 2nd medium If the angle of incidence is increased beyond the critical angle, the light rays will be totally reflected back into the incident medium. This effect is called total internal reflection.
