Observation and explanation of Activity 10.13 Class 10 Science

We place a burning candle on the left side of the concave lens at different positions and find the images. We observe an erect virtual and smaller image is formed on the same side of the lens.

The image is not real so it cannot be received on the screen.

(i)     At infinity - When the object is placed at infinity, image is formed at Focus on the same side of the concave lens.

Nature of image – Virtual and erect

Position of image –  at F₁

Size of image – highly diminished

(ii)     Between infinity and lens at any place - When the object is placed between infinity and lens, image is formed at the same side of the concave lens.

Nature of image – Virtual and erect

Position of image – on the same side of the lens as the object

Size of image – diminished

Position of the object	Position of the image	Size of the image	nature of the image
At infinity	At F1	Highly diminished	Virtual and erect
Between infinity and lens	same side to that of object	Diminished	Virtual and erect
