In your laboratory you trace the path of light rays through a glass slab for different values of angle of incidence \[\mathbf{(}\angle \mathbf{i)}\] and in each case measure the values of the corresponding angle of refraction \[\mathbf{(}\angle r\mathbf{)}\] and angle of emergence\[\mathbf{(}\angle e\mathbf{)}\]. |
On the basis of your observations your correct conclusion is: |
(a) \[\angle i\] is more than \[\angle r,\] but nearly equal to \[\angle e\] |
(b) \[\angle i\] is less than \[\angle r,\] but nearly equal to \[\angle e\] |
(c) \[\angle i\] is more than \[\angle e,\] but nearly equal to \[\angle r\] |
(d) \[\angle i\] is less than \[\angle e,\] but nearly equal to \[\angle r\] |
Answer:
(a) \[\angle i\] is more than \[\angle r,\] but nearly equal to \[\angle e\]
