Question

an object is kept 40cm in front of a concave mirror of focal length 20cm find the position and nature of the image draw a ray diagram to show the formation of image in the case

Answer 1

the position of the image is on the same sideand that is at a distance of negative 40 cm from the mirror
the nature of the image is real and inverted

Answer 2

Answer:

Explanation:

u = -40

f = -20

V=?

1/u +1/v =1/f

1/ -40 + 1/v = 1/-20

1/v = -2+1/40

= -1/40

By cross multiplying

v = -40

Nature =real and inverted
