Question

An object 30 cm tall is located 10.5 cm from a concave mirror with focal length 16 cm. Find the location and height of the image​

Answer 1

Explanation:

u= -10.5

h=30

f=-16 cm

1/f=1/v+1/u

-1/16=1/v-1/10.5

1/v=-1/16+10/105

-1/16+2/21

-21+32/336

11/336

v=336/11

v= 30.5 cm(location)

m=-v/u=h¹/h

-30.5/-10.5=h¹/30

-915/-10.5

87.14 cm( height of the image)

hope it helps
