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

A simple microscope is rated 5 X for a normal relaxed eye. What will be its magnifying power for a relaxed far sighted eye whose near point is 40 cm .

For a normal relaxed eye, a simple microscope is rated as 3X. What will be the rating of a microscope for a relaxed farsighted eye whose near point is 50 cm.

A magnifying glass is rated 6X for a normal relaxed eye. For a relaxed farsighted eye whose near point is 50 cm, then what will be its magnifying power?

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?

" If the focal length of a magnifier is "5cm" calculate,the magnifying power of the lens for relaxed eye "

If the focal length of the objective lens and the eye lens are 4 mm and 25 mm respectively in a compound microscope. The length of the tube is 16 cm . Find its magnifying power for relaxed eye position

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 simple microscope is a combination of two lenses in contact of powers +15 D and +5D. Calculate the magnifying power of the microscope, if the final image is formed at 25 cm from the eye.

The focal lengths of the objective and eye - lens of a microscope are 1cm and 5 cm respectively. If the magnifying power for the relaxed eye is 45 , then the length of the tube is
