Looking at a surface between glass (index of refraction of 1.5) and oil (index of refraction of 1.25), Which way can the light travel to give total internal reflection, from glass to oil or oil to glass? What is the critical angle for light going that direction? [56.4 degree] If light is instead incident at 60 degree, describe what happens to the light when it hits the surface. If light is instead incident at 50 degree, describe what happens to...

A glass plate whose index of refraction is 1.56 is immersed in a liquid. The surface of the glass is inclined at an angle of 42.0° with the vertical. A horizontal ray in the glass is incident on the interface. When the liquid is a certain alcohol, the incident ray arrives at the interface at the critical angle. What is the index of refraction of the alcohol? • Draw a ray diagram • Draw a line normal to the boundary...

Question 19 of 31 > The index of refraction for a certain type of glass is 1.637 for blue light and 1.607 for red light. A beam of white light (one that contains all colors) enters a plate of glass from the air, r1, at an incidence angle of 37.05. What is the absolute value of 8, the angle in the glass between blue and red parts of the refracted beams? 18] Question 18 of 31 > The core...
