In this figure the path of the light passes from air to glass. Calculate the index of refraction
n1 = air = 1
n2 = glass = ?
Sin theta 1 = 30degrees
sin theat 2 is = 20 degrees

formula used n2 = n1*sin theta 1 / sin theta 2

sin of 30/ sin of 20 = n2 = 1.46 is this correct
hope the attachment went through will have to see before making judgement
