Calculate Index of Refraction: Air to Glass

[cowgiljl]

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

Yeah it is

Yes, your calculation is correct. The index of refraction from air to glass is 1.46. This means that light travels approximately 1.46 times slower in glass compared to air. This is due to the different density and optical properties of air and glass. The index of refraction is an important factor in determining the behavior of light as it passes through different materials, and is essential in understanding phenomena such as refraction and total internal reflection.
