Question

Explain with an experiment for observing the various types of images formed by a concave mirror and to measure the object and image distance from the mirror.​

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
