Question

A concave mirror used for rear view on an automobile has a radius of curvature 30m, if bus is located 5m from the mirror find position, nature & size of image? ​

Answer 1

Explanation:

Radius of curvature=30m

focal length=Radius of curvature/2

30/2=15m

object distance=-5m

Image distance=?

1/f=1 /u +1/v

1/15 =1/-5 + 1/v

1/v= 1/15 +1/5

1/v = 1+3/15

1/v = 4/15

1/v= 1/0.267

v= 0.267
