A simple microscope is rated 5X for a normal relaxed eye. What will be its magnifying power for a farsighted man whose near point is 30cm

A simple microscope is rated 5 X for a normal relaxed eye. What Will be its magnifying power for a relaxed farsighted eye whose near point is 40 cm?

In a simple microscope, if the final image is located at infinity then its magnifying power is

The magnifying power of a simple microscope is given by 1+D/f , where D is the least distance for clear vision. For farsighted persons, D is greater than the usual. Does it mean that the magnifying power of a simple microscope is greater for a farsighted person as compared to a normal person? Does it mean that a farsighted person can see an insect more clearly under a microscope than a normal person?

The focal lengths of the objective and eyepiece of a telescope are 60 cm and 5 cm respectively. Find as magnifying power (P) for normal adjustment and when the image forms at near point.

A simple microscope has a magnifying power of 3.0 when the image is formed at the near point (25 cm) of a normal eye. (a) What is its focal length? (b) What will be its magnifying power if the image is formed at infinity?

(a) An object is seen through a simple microscope of focal length 12cm . Find the angular magnification produced if the image is formed at the near point of the eye which is 25cm away from it. (b) A 10D lens is used as a magnifier. Where should the object be placed to obtain maximum angular magnification for a normal eye (near point = 25cm) ?

An object is seen through a simple microscope of focal length 12 cm. Find the angular magnification produced if the image is formed at the near point of the eye which is 25 cm away from it.

A person uses + 1.5 D glasses to have normal vision from 25 cm onwards. He uses a 20 D lens as a simple microscope to see an object. Calculate the maximum magnifying power, if he uses the microscope (a) together with his glasses (b) without the glasses.

In a simple microscope of focal length 5 cm final image is formed at D , then its magnification will be

A thin convex lens of focal length 5 cm is used as a simple microscope by a person with normal near point (25"cm") . What is the magnifying power of the microscope.?
