Question

Assertion (A): Lateral displacement is directly proportional to thickness of the glass slab.

Reason (R): Lateral displacement increases with the thickness of the given slab.

(a) Both ‘A’ and ‘R’ are true and ‘R’ is the correct explanation of ‘A’.

(b) Both ‘A’ and ‘R’ are true but ‘R’ is not the correct explanation of ‘A’.

(c) ‘A’ is false but ‘R’ is true.

(d) ‘A’ is true but ‘R’ is false.​

Answer 1

Solution :

a) Both ‘A’ and ‘R’ are true and ‘R’ is the correct explanation of ‘A’.

Explanation :

Lateral Displacement $\sf=\dfrac{t\sin(i-r)}{\cos(r)}$

Hence , Lateral Displacement is directly proportional to thickness of glass slab .
