Question

A convex mirror used on a bus has a focal length of 200 cm. If a scuter is located 400cm . From this mirror

Answer 1

Answer:

f = 200

u  400

1/∨ + 1/u = 1/f

1/∨ = 1/f - 1/u

1/∨ = 1/200 - 1/400

1/∨ = 400-200/80000

1/∨ = 200/80000 = 2/800

1/v = 1/400

v = 400 cm

m = -v/u

m = -400/400

m = -1

therefore the image is real and inverted
