Find the nature and position of images, when an object is placed at different places on the principal axis of a concave mirror.
Aim: Observing the types of images and measuring the object distance and image distance from the mirror.
Material required: A candle, paper, concave mirror of known focal length, V - stand, measuring tape or meter scale.
- Place the concave mirror on V - stand, a candle and meter scale.
- Keep the candle at different lengths from the mirror along the axis and by moving the paper find the position where you get the sharp image on paper.
- Note down the observations in the following table.
