Grade 12Wave Optics
A cubical block of glass of refractive index n1 is in contact with the surface of water of refractive index n2. A beam of light is incident on vertical face of block. After rrefraction, a total internal reflection at the base and refraction at the opposite vertical face, the ray emerges out at an angle (a) .The valve of (a) is given by?
