Question

Find the nature and position of images, when an object is placed at different places on the
principal axis of a concave mirror.
​

Answer 1

Answer:

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.

Procedure :-

• 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
• This imaginary line is called the principal axis or optical axis of the mirror. ... Rays of light parallel to the principal axis of a concave mirror will appear to converge on a point in front of the mirror somewhere between the mirror's pole and its center of curvature.
