A concave mirror is placed inside water ...

A concave mirror is placed inside water its shining surface upwards and principal axis vertical as shown in figure. Rays are incient parallel to the principal axis of the concave mirror. Find the position of the final image.

Text Solution

Verified by Experts

We have,
`u = -oo, f = -20cm`
So, `v = -20cm`
So, `d = 10cm`
`:. D' = (d)/(mu_("rel)) = (10cm)/(4//3)`
`(30)/(4) cm = 7.5cm`
