Intuitive Reason of Bending

Q. Match the proper entries from column- $2$ to column- 1 using the codes given below in the columns. Deviation in the Column-II is the magnitude of total deviation (between incident ray and finally refracted or reflected ray) which lies between $0^{\circ }$ and ${180}^{\circ }.$ Here $n$ represents refractive index of medium.

Column-I	Column-II
(p)	(1) deviation in the light ray is greater than ${90}^{\circ }$
(q)	(2) deviation in the light ray is less than ${60}^{\circ }$
(r)	(3) deviation in the light ray is greater than ${60}^{\circ }$ but less than ${90}^0$
(s)	(4) Speed of light remains same after falling on the boundary of two mediums.

1. p-3, 4; q-1, 4; r-4; s-2
2. p-1, 3, 4; q-2; r-3, 4; s-2, 3
3. p-4, 2; q-2, 4; r-1, 4; s-3
4. p-1, 4; q-3; r-3, 4; s-3
