Rays of light fall on a glass slab `(mugt1)` as shwon in figure. If `mu` at `A` is maximum and at `B` it is minimum, then what will happen to these rays?
A. They will tilt towards `A`
B. They will tilt towards `B`
C. They will not deviate
D. There will be total internal reflection
A. They will tilt towards `A`
B. They will tilt towards `B`
C. They will not deviate
D. There will be total internal reflection
(c) For normal incidence, Whatever be refractive index.
`l=0, r=0`, so there is no deviation of ray.
