Question 42

Multiple Choice

Which one of the following expressions determines the critical angle for quartz (n = 1.5) immersed in oil (n = 1.1) ?


A) Which one of the following expressions determines the critical angle for quartz (n = 1.5) immersed in oil (n = 1.1) ? A)   = 1.5/1.1 B)  = sin-¹ (1.1/1.5)  C)   = sin (1.1/1.5)  D)   = tan-¹ (1.1/1.5) = 1.5/1.1
B) 11ec9dfe_2a8e_1022_8d20_79f89e357768_TB6393_11= sin-¹ (1.1/1.5)
C) 11ec9dfe_2a8e_1022_8d20_79f89e357768_TB6393_11 = sin (1.1/1.5)
D) 11ec9dfe_2a8e_1022_8d20_79f89e357768_TB6393_11 = tan-¹ (1.1/1.5)
