when light passes from more dense midium to less dense midium..?

Question

where are the incident and refracted rays located in relation to the normal??

uhh sorry for misspelling!

Answer 1

The densities (mass per unit volume) are actually irrelevant. What matters is the OPTICAL density, which is measured by the index of refraction of a substance, which is the ratio of the speed of light in the medium to c, the speed of light in a vacuum.The incident and refracted rays will be on opposite sides of the normal, and the angle of the incident ray in the more optically dense medium will be smaller than the angle of the refracted ray in the less optically dense medium. The relationship is given by:

n1sin(theta1)=n2sin(theta2)

where n1,n2 are the indices of refraction for the 2 media and theta1,theta2 are the corresponding angles made by the light ray with the normal.

Answer 2

you would probably have better luck getting people to answer if you spelled the word MEDIUM correctly...
