Optics critical angle
WebOct 27, 2024 · The critical angle for water (which would apply to raindrops) is 48 degrees (relative to the normal). Therefore, if light strikes the back of a raindrop at an angle greater than 48 degrees, it will be reflected back. If the angle is smaller than 48 degrees, the light will simply pass on through. What is the value of critical angle in optical ... WebNov 29, 2024 · Critical Angle is the angle of incidence which provides a 90 degree angle of refraction.

WebApr 2, 2024 · so, • Sin (θ c )/ Sin (90) = n 2 /n 1. • Critical angle (θc)= arcsin (n2/n1) Example: Refraction from water to air (refractive index of water is 1.33) θc = arcsin (1/1.33) = 49 degrees. If the angle of incidence of the light ray exceeds the θ c then the light ray comes back into the same medium after reflection at the interface.
