Calculate the critical angle for the light traveling from glass (1.43) to air ( =1.00). Express your answer in degrees. Normal format with 3 SF.

Consider a light ray that enters and exits a prism as shown below. Suppose the material of the prism is unknown but the surrounding material has index of refraction n, = 1.3. Find the index of refraction for the material of the prism. n2 n1 22° 38° 9. n, = А. 1.479 D. 1.586 В. 1.635 Е. 1.333 С. 1.389 F. 1.527

White light strikes the left face of a 300-60°-90° glass prism along a normal to the surface (so there is no refraction there). The light moves horizontally through the prism and strikes the right face at an angle of 30.00° to the normal. As the light leaves the prism it is refracted at the right face. DO ALL CALCULATIONS TO 4 SIGNIFICANT FIGURES! What is the DIFFERENCE in the refracted angles for red light (ned = 1.567) and violet (niolet = 1.613)? Find (8, - e,), where e, and e, are the angles of refraction for violet and red light. 313 PM

Consider white light incident on a plate of crown glass. The angle of incidence is 29.4 degrees.   What is the difference in the angle of refraction between red (660 nm) and blue (470 nm) rays? (Indices of refraction: nred= 1.52; nblue= 1.531).           The ray now travels inside the glass. What is the minimum angle of incidence for the red ray to be totally reflected?

A block of glass that has an index of refraction of 1.55 is completely immersed in water (n = 1.33). 1) What is the critical angle for light traveling from the glass to the water? (Express to 3 sig fig)
