Question

A convex mirror used for rear - view on an automobile has a radius of curvature of 3.00m. if a bis is located at 5.00 m from this mirror ,find the position,nature and size of the image.​

Answer 1

Answer:

v=?

u=-5m

f=3/2. (R=2f)

using mirror formula

1/v+1/u=1/f

we have to find image distance

so the formula will be

1/v=1/f-1/u

putting values now

1/v=2/3-(-1/5)

1/v=2/3+1/5

1/v=13/15

(v=15/13)

now magnification

m=-v/u

m=-15/13x1/-5

(m=3/13)

image formed is virtual and erect
