A block of glass with flat sides is surrounded by air. A ray of light traveling in the glass (refractive index na) is incident on the flat interface with air at the top surface of the block of glass. You observe that no light is refracted into the air if the incident ray in the glass has an angle of incidence (measured relative to the normal to the surface of the glass) greater than 35.5°. What is the refractive index...

An optical fiber consisting of a core made of glass (n = 1.667) surrounded by a crown glass lining (n = 1.523). A ray of light in the air enters the fiber at an angle φ 1 with respect to the normal one. What is φ 1 if this light also affects the core cladding interface at an angle that barely exceeds the critical angle?

A glass prism has a cross section of an isosceles triangle with a = 55.2º. A light beam is incident at an angle of 0 = 53.2° and passes through the prism parallel to the base of the triangle as shown in the figure. What is the index of refraction of the glass? (Recall that the sum of all the internal angles of a triangle is 180°.).

A block of plastic (n = 1.6) is immersed in water as shown in image below. A light ray is incident on the top face at a distance of x = 3 cm from the top righ corner at an angle 01 = 45° with a line normal to the top surface. The ray then exits the block on the righ side at point P. Determine the angle 02 which the ra exits the block. Then find y, the distance...
