A plane mirror and a concave mirror (f = 8.40cm) are facing each other and are separated by a distance of 22.0 cm. An object is

lesya [120]

Answer:

The distance of the image produced by the concave mirror is 11.27 cm.

Explanation:

Given that,

Focal length = 8.40 cm

Distance between object and plane mirror = 11.0 cm

Distance between plane mirror and concave mirror = 22.0 cm

We need to calculate the object distance

$u =11.0+22.0 = 33.0\ cm$

We need to calculate the distance of the image

Using formula of distance of the image

$v=\dfrac{uf}{u-f}$

Where, u = Object distance

f = focal length

Put the value into the formula

$v=\dfrac{33.0\times8.40}{33.0-8.40}$

$v=11.27\ cm$

Hence, The distance of the image produced by the concave mirror is 11.27 cm.
