MHT CET Physics question
The XZ-plane separates two media A and B with refractive indices and , respectively. A ray of light travels from A and B. Its directions in the two media are given by the unit vectors and respectively, where and are unit vectors in the x and y-directions. Then,
Answer: (A)
Solution
The normal to the XZ-plane is along y, so for each ray is the x-component of its unit direction (, ); Snell's law \sin$ i =
