Question

(g) 8, = 60° 32.10 and o (b) 32.1 12 = 1.0 ing a -frac- Figure 32.15 in 02. A ray of light travelling through a block of transparent material of refractive index n, enters a medium with a refractive in dex of n = 1.0 at an incident angle of as shown in Figure 32.15. the What is the refracted angle when: (a) , = 30° and n = 1.33 (b) 0, = 35° and n = 1.33 (c) 0,= 40° and n = 1.33 (d) 0, = 45° and n = 1.33 0, = 25° and n = 1.55 (f) 0,= 30° and n = 1.55 (g) 0, = 35º and n = 1.55 (h) 0,= 40° and n = 1.55 What is the critical angle when n, is: (i) 1.05 (1) 1.33 edium (k) 1.55 ock of (1) 1.75

only letters (a) and (j)

Answer 1

(") from snell's Town 1.33 Then - → Singer - Sing, = 2.33%} 0 = sir" [133] 02. = 41.687 (j) for critical Angie, O2 = 90 = Oca soñ (3:30) loc = 48.75 Degree
