Question

an object is placed 24 cm from a concave mirror its image is inverted and doubles the size of the object find the focal length of the mirror and the position where the image is formed

Answer 1

your solution.........

Answer 2

u = -24

m = -2

m = -v/u

-2 = -v/u

v = -24×2

v = -48

Image of is -48

Formed in front of the mirror

1/f = 1/v + 1/u

1/f = 1/-48 + 1/-24

1/f = -1-2/48

1/f = -3/48

1/f = -1/16

f = -16

focal length of the mirror f = -16
