The focal length of objective and eye lens of a microscope are `4 cm` and `8 cm` respectively. If the least distance of distinct vision is `24 cm` and object distance is `4.5 cm` from the objective lens, then the magnifying power of the microscope will be

The focal lengths of objective and eyepiece of a compound microscope are 0.5 cm and 1.5 cm respectively . If the least distance of distinct vision is 25 cm and magnification is 500 then what is the distance between objective and eyepiece?

The focal lengths of the objective and eye piece of a compound microscope are 4 cm and 6 cm respectively. If an object is placed at a distance of 6 cm from the objective, calculate the magnification produced by the microscope. Take distance of distinct vision = 25 cm .

The focal lengths of the objective and eye-piece of a compound microscope are 4 cm and 6 cm respectively. If an object is placed at a distance of 6 cm from the objective, what is the magnification produced by the microscope? Distance of distinct vision = 25 cm.
