Sir pls solve this ?
Dear Student,
1.
The angle which the incident ray makes with the normal to the surface at the point of incidence is called angle of incidence (i).
For i = 0o, light passes through the interface without bending. Thus, for light ray to bend, i must be greater than 0o. So, 1st option is necessary.
Both the media must be transparent, then only light can propagate through. So, 2nd option is also necessary.
A light bends when it encounters an interface separate two media of different refractive indices. Thus, 3rd option is necessary.
Any light when encounters an interface separating two media of different refractive indices will bend. Specific colour is not a necessary criteria. Thus, correct option is the 4th one.
2.
When light travels from rarer medium to denser medium it bends towards the normal while when it travels from a denser medium to a rarer medium it bends away from the normal. Thus, looking into the plots in the option, 2nd option is CORRECT.
Please post the remaining question is a separate post so that our experts can provide you with detailed answer.
