Question

An object 2cm high produce areal image 3 cm high, when placed at a distance of 15cm from concave mirror. Calculate the position of the image. (HOTS) flows and a two characteristics of the I hope it helpful ​

Answer 1

Answer :-

Given :-

$H_{i} = 3 cm\\\\H_{o} = 2 cm$

U = -15 cm

Solution :-

$\frac{H_i}{H_o} = \frac{-V}{U}$

⇒ $\frac{3}{2} = \frac{-V}{U}$

⇒ V = 45/2

⇒ V = 22.5 cm

⇒ As the image is formed beyond the concave mirror, the sign convention for image distance need to be positive .
