Question

an object is kept at a distance of 5cm in front of a convex mirror of a focal distance 10cm. calculate the maginification of the image​

Answer 1

Answer:

1 ÷ f = 1 ÷ v - 1 ÷ u

1 ÷ 10 = 1 ÷ v - 1 ÷ -5

1 ÷ 10 + 1 ÷ 5 = 1 ÷ v

1 + 2 ÷ 10 = 1 ÷ v

3 ÷ 10 = 1 ÷ v

v = 10 ÷ 3 _ _ _1

v = 3.33cm

m = -v ÷ u

m = 10 ÷ 3 ÷ -5

m = 10 ÷ 3 × 1 ÷ 5

m = o.666

position of image = behind the mirror

nature of image = virtual and erect

Hope this helps
