Question

A convex mirror used on an automobile has a focal length of 1.5m if a truck is located 5m from this mirror find the position of the image

Answer 1

Answer:

2.14

Explanation:

given:-

Type of mirror = convex mirror

position of object, u = 5m I.e.- 5

focal length of mirror,f = 1.5m i.e.,+1.5

to find:-

position of image, v

solution:-

By mirror formula we get

$\frac{1}{f} = \frac{1}{v} + \frac{1}{u}$

i.e.

$\frac{1}{1.5} = \frac{1}{v} + \frac{1}{ - 5}$

so,

$\frac{10}{15} = \frac{1}{v} - \frac{1}{5}$

$\frac{1}{v} = \frac{10}{15} - \frac{1}{5}$

i.e.

$\frac{1}{v} = \frac{10 - 3}{15}$

i.e.

$v = \frac{15}{7}$

i.e.

$v = 2.14(approx.)$
