Two identical glass slabs of same thickness are joined to form an `L` shape as shown. A ray is incident on the combination as shown (in the plane of paper). The final emergent ray will choose, incorrect options(s):

A

Come out at point A in the same direction as that of original ray.

B

Come out at point A but not in the same direction as that of origional ray.

C

Does not come out at point A but is in the same direction as original ray.

D

Does not come out at point A and it is not in same direction as origional ray.

Text Solution

Verified by Experts

The correct Answer is:
B, C, D

Option B,C,D are incorrect
An ideal monatomic
`TV^(8-1)=` constant.
`a-1=(1)/(2)`
`a=(3)/(2)` ltgbrgt `C=C_(V)-(R)/(a-1)`
`C=C_(V)-2R`
As V increase, temperature decreases hence internal energy decreases.
