What the answers to physics questions?
1. Light in the air Line of ordinary glass into the air boundaries of the incident angle of 1 ^ exactly 3.0x10. 1.65 if the refractive index of the glass, in what respect the top Refracted angle in the glass and Ray?) 56 b) a 46 C) 29 d) to 18 C) 29 2. Stone 17.0 cut diamonds that light is refracted at an angle to normal. 45.0 What is the refractive index of the incidence angle of the diamond?) 2.13 b) a 1.74 C) 1.23 d) 2.42 for a ton of answers I need! Thank you !!!!!!!!!!!
n_i * sin (b) = n_r * sins (R) 1. Sin (R) '= (n_i / n_r) ※ sin (b) Study = arcsin ((n_i / n_r) ※ sin (b)) Study = arcsin ((1/1.65) ※ sin (30)) of = arcsin ((1/1.65) * 0.5) = 17.64 degrees As of: d) 2 to 18. n_r = n_i * a sin (B) / sin (R) of the n_r = 1 * sin (45) / sin (17) n_r = 2.42 answer: d) 2.42 in
