Question

an object is placed at a distance of 20cm from a convex lens of a focal length 10cm find the image distance and nature of the image .​

Answer 1

Answer:

Here we have, U(object distance) = -20cm F(focal length) ... Find the nature and position of the image? .... A convex lens of focal 15 cm is placed on a plane mirror .

Explanation:

It is given that,

Object distance from the convex lens, u = -20 cm

Focal length of the convex lens, f = +10 cm

If v is the position of image with respect to the mirror. It can be calculated using lens formula as :

v = 20 cm

So, the image will be formed at a distance of 20 cm behind the lens. If m is the magnification of the lens,

m = -1 (image is real and inverted)
