Question

A man stands 2 meters away from a concave mirror of 1 meter focal length. Calculate the distance of the image of the man from the pole of the mirror. Will the image formed be real or virtual? Also calculate the image magnification and find the image size and its nature

please do correctly!!!!

Answer 1

Answer:

u=-2

f=-1

v=?

By using mirror formula

1/u+1/v=1/f

1/-2+1/v=1/-1

1/-2-1/-1=1/v

1-2/2=1/v

-1/1=1/v

1/v=-1/1

v=-1 [sign will not change]

m=-v/u

m=-(-1)/-2

m=-1/2

m=-0.5

Image will be lager than the object and becuz Magnification is having minus [-] sign so the nature of image will be Real and inverted.

Explanation:

Object distance, focal length,image always take with the sign[-]
