Question

find the coordinates of image of point (0,-2) and angle 30°​

Answer 1

Answer:

To find the co-ordinates of image of point object P formed after two successive reflection at concave mirror and then at convex.

Solution:

Consider concave mirror (M1) from figure, 

Object distance, u1=−20cm

Focal length of the mirror, f1=−15cm

Applying mirror formula, 

f11=v11+u11⟹v11=f11−u11⟹v11=−151−−201⟹v11=60−4+3⟹v1=−60cm

Magnification, m1=−u1v1=
