Answer 1

For a simple microscope, the magnification $M$ is given by $1 + \frac{D}{f}$ where D is least distance of distinct vision.

$M = 1 + \frac{2 5}{1 0} = 3.5$

Answer. (C) 3.5

Answer 2

For a simple microscope, the magnification

M

is given by

1 + \frac{D}{f}

where D is least distance of distinct vision.

M = 1 + \frac{2 5}{1 0} = 3.5

Answer. (C) 3.5

The least distance of distinct vision is 25cm. The focal length of a convex lens of a simple microscope is 5 cm. Its magnifying power if the image is at near point

A simple microscope consists of a concave lens of power 10D and a convex lens of power 15 D. Its magnification at near point is
(least distance of distinct vision, D $=$ 25 cm)

The magnifying power of a simple microscope is $6$ The focal length of its in meters will be, if least distance of distinct vision is $25 c m$

The focal length of a convex lens is 10 cm. The magnifying powers when it is used as a magnifying glass to form the image at (i) near point and (ii) far point are :

A simple microscope has a focal length of 5cm. The magnification at the least distance of distinct vision is
