Question

1. Determine the image distance and image height for a 6.0 tall object placed from 40.15cm from a convex lens having a focal length of 10.0cm

Help Please!!! Straight Answer!​

Answer 1

Answer :

Image distance = 13.31cm

Image height = -2

Step-by-step Explanation :

Given : u = - 40.15cm

f = 10cm

H(obj) = 6cm

To find : v = ?

H(ima) = ?

We know that ,

1/f = 1/v - 1/u

1/f + 1/u = 1/v

1/10 - 1/40.15 = 1/v

40.15 - 10 / 401.5 = 1/v

1/13.31 = 1/v

v = 13.31

Also,

H(ima) / H(obj) = v/u

H(ima)/6 = 13.31 / -40.15

H(ima) = 6 × 13.31 / -40.15

= -1.98

H(ima) = -2
