Question

In a simple microscope, if the final image is located at 25 cm from the eye placed close to the lens, then the magnifying power is: (A)  (25/f)  (B)  1+(25/f)  (C)  (f/25)  (D)  (f/25)+1

Magnification of simple microscope m=1+(D/f) D = distance of final image So, m=1+(25/f)

Q. In a simple microscope, if the final image is located at 25 cm from the eye placed close to the lens, then the magnifying power is:

$\frac{25}{f}$

$1 + \frac{25}{f}$

$\frac{f}{25}$

$\frac{f}{25} + 1$

Magnification of simple microscope $m = 1 + \frac{D}{f}$ D = distance of final image So, $m = 1 + \frac{25}{f}$

Q. In a simple microscope, if the final image is located at 25 cm from the eye placed close to the lens, then the magnifying power is:

f25​

1+f25​

25f​

25f​+1

Magnification of simple microscope m=1+fD​ D = distance of final image So, m=1+f25​

$\frac{25}{f}$

$1 + \frac{25}{f}$

$\frac{f}{25}$

$\frac{f}{25} + 1$

Magnification of simple microscope $m = 1 + \frac{D}{f}$ D = distance of final image So, $m = 1 + \frac{25}{f}$
