Question

A glass slab is placed in the path of convergent light.. The point of convergence of light .......... .

• A. moves away from the slab
• B. moves towards the slab
• C. remains at the some point
• D. undergoes a lateral shift

Answer 1

Answer: (A)

moves away from the slab

$\begin{array}{c}\text{As the}\mu \text{(refractive index of glan) is more than that of air}\\ \text{the light after entering it moves close to normal; travels}\\ \text{for fosome path (width of slab) and then again moves far from}\\ \text{normal, ofter going back to air o the point of convergence is shifted.}\\ \text{Hence obtion 'A' is corret.}\end{array}$
