Question

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

Answer 1

Answer:

Given: R=3m

f=1.5 m

u=-5 m

v=?

Explanation:

we know f=1/v + 1/u

1.5=1/v+ 1/-5

1/v= 1.5-1/-5

= 15+2/10

=17/10

=1.7 m

therefore position of image is 1.7 m at the back of mirror

nature is virtual and erect

size is enlarged

hope it helps...

Answer 2

Answer:

given

R=3m

f=1.5m

U=-5m

to find is V

Explanation:

F=1/v+1/U

1.5 = 1/v + 1/-5

1/v = 1.5 - 1 / -5

=15+20/10

= 1.7 m
