A compound microscope having `f_(0)` = 7 mm, `f_(e)` = 20 mm and distance between the lenses is 20 cm. If image is formed at least distance of distinct vision then magnifying power ?

The focal of the objective and the eyepiece of a compound microscope are 0.5 cm and 1 cm respectively . The distance between the lenses is 16 cm . If the final image is formed at the least distance of distinct vision i.e at 25 cm ,determine the magnifying power of the instrument .

A convex lens of focal length 10 cm and imag formed by it, is at least distance of distinct vision then the magnifying power is

A convex lens of focal length 10 cm and imag formed by it, is at least distance of distinct vision then the magnifying power is

The focal lengths of the objective and the eyepiece of a compound microscope are 1 cm and 5 cm respectively and the distance between the centres of the lenses is 15 cm . If the final image is formed at the least distance of distinct vision , what is the magnifying power of the microscope ?

In a simple microscope, the lens is held at a distance d from the eye and the image is formed at the least distance d of the distinct vision from the eye. What is the magnifying Power of the microscope ? Where f is the focal length of the lens.

Draw a ray diagram of compound microscope for the final image formed at least distance of distinct vision?

The focal lengths fo the lens of a simple microscope is 5 cm . If the lens is held near the eyes the image is formed at 25 cm . i.e ., at the least distance of distinct vision. What is the magnifying power of the instrument ?
