WebThis of course is impossible, and the light in such cases is completely reflected by the boundary, a phenomenon known as total internal reflection. The largest possible angle of incidence which still results in a refracted ray is called the critical angle; in this case the refracted ray travels along the boundary between the two media. WebWhen the angle of refraction is equal to \(90^\circ\), the angle of incidence is called the critical angle, \(\theta_{c}\). ... This is called total internal reflection.

WebStep 4: Calculate the critical angle of diamond (cd) sin (c d) = 1 ÷ 2.4 = 0.4167. c d = sin –1 (0.4167) = 24.6 = 25°. Step 5: Compare the two values and write a conclusion.
