- I Use A Converging Lens Of 300 Mm Focal Length To Project The Image Of A A4 Transparency Height Of 29 7 Cm Onto A Wall 1 (93.57 KiB) Viewed 63 times
I use a converging lens of 300 mm focal length to project the image of a A4 transparency (height of 29.7 cm) onto a wall which is at a distance of 2.10 m from the lens. For a focussed image the distance from the transparency to the lens must be mm (write 3 significant figures without a possible negative sign). The algebraic magnification of the projection is (write 1 significant figures). The height of the image is cm (write 3 significant figures without a possible negative sign).
