Question

Describe the nature of the image formed when the object is placed at a distance of 20cm from a concave mirror of focal length 10cm​

Answer 1

Answer:

Here, u = - 20 cm; f = -10 cm

1/v + 1/u = 1/f

⇒ 1/v + 1/(-20) = 1/-10

⇒ 1/v = 1/20 – 1/10 = -1/20

∴ v = -20 cm

So, image will be real and inverted .
