Question

What do you infer from the experiment which you did to measure the object distance and image distance

Answer 1

Hey there!

Brief explanation of the experiment : We arrange a spherical concave mirror on v holder and a candle is placed in front of it. We move the candle to different places. We measure image distance and object distances . Focal length of the mirror is 15cm

Inference : We infer from this experiment that, As candle moves from focus to infinity, it size decreases. At distance = 30cm from the mirror, The image so formed is of same size and same distance from the mirror.

We also deduce a formula that, Mirror formula
$\frac{1}{f} = \frac{1}{u} + \frac{1}{v}$

Hope helped!

Answer 2

Answer:

From the experiment of measuring object distance and image distance we can observe the nature of image formed by concave mirrors and we can infer that concave mirror form both real and virtual image
