Question

A beam of light is converging towards a certain point. A parallel sided
glass plate is introduced in the path of converging beam. How will the
point of convergence shifted.​

Answer 1

Answer:

ask it on Google coz it will help you.

Answer 2

Answer:

t[1-(1/n)]nearer

Explanation:

when glass plate of thickness t is introduced the optical path is increased by (t/n).so the convergence point shifts by t-(t/n) that is to t[1-(1/n)]nearer
