Question

An object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm, find the position and nature of the image​

Answer 1

Answer:

An object is placed at a distance of 10cm from a convex mirror of focal length 15cm. ... Since the image is formed behind the convex mirror, therefore, the nature of image is virtual and erect.

Explanation:

U= -10 cm

f= 15 cm

1/f = 1/v + 1/u

So, 1/v= 1/f - 1/u

1/v= 1/15 + 1/10

1/v = (2+3)/30 (lcm)

Therefore v=5/30 = 6 cm

Hence the image is formed behind the mirror and therefore it is virtual and erect
