Question

1)find the distance of image when an object is placed on the central axis at a distance in front of a concave mirror whose radius of curvature is 8 cm​

Answer 1

Answer:

Given, u= -10cm,R= -8cm=2f ,f= -4cm

v=?

From the mirror formula:

1/v + 1/u = 1/f

1/v - 1/10= 1/-4

1/v = -6 by 10/4

v = -20/3cm
