Question

a glass slabe is placed in the path of convergent light the point of convergence of light ​

Answer 1

Answer:

The cube root of 729, denoted as 3√729, is a value which after getting multiplied by itself thrice gives the original value. This is the usual definition of the cube root of a number. Let us say, 'n' is the value of 3√729, then n × n × n = n3 = 729.

Answer 2

Answer:

If the glass slab is placed in the path of convergent light ,the point of convergence or focus will shift away from the glass slab as the light on passing through glass will bend towards the normal and after coming out in air, light will converge out at a point away from the glass slab.
