In a compound microscope, the focal lengths of two lenses are 1.5 cm and 6.25 cm an object is placed at 2 cm form objective and the final image is formed at 25 cm from eye lens. The distance between the two lenses is

In a compound microscope, the focal length of the objective and the eye lens are 2.5 cm and 5 cm respectively. An object is placed at 3.75cm before the objective and image is formed at the least distance of distinct vision, then the distance between two lenses will be ( i.e. length of the microscope tube )

The two lenses of a compound microscope are of focal lengths 2 cm and 5 cm. If an object is placed at a distance of 2.1 cm from the objective of focal length 2 cm the final image forms at the final image forms at the least distance of distinct vision of a normal eye. Find the magnifying power of the microscope.

The focal length of objective and the eyepiece of a compound microscope are 1cm and 5cm. An object is placed at a distance of 1.1 cm from the objective and if the final image is formed at infinity the magnifying power and distance between the lenses are respectively

In a compound microscope consisting of two convex lenses of focal lengths 1.5 cm and 10 cm, the object is 2 cm from the objective and the final image is formed at the least distance of distinct vision (D=25cm) . Find the distance of separation of the two lenses.

When an object is placed 40cm from a diverging lens, its virtual image is formed 20cm from the lens. The focal length and power of lens are

A compound microscope consists of two convex lenses of focal length 2 cm and 5 cm. When an object is kept at a distance 2.1 cm from the objective, a virtual and magnified image is formed 25 cm from the eye piece. Calculate the magnifying power of the microscope.

If the focal length of objective and eye lens are 1.2 cm and 3 cm respectively and the object is put 1.25cm away from the objective lens and the final image is formed at infinity. The magnifying power of the microscope is

A compound microscope consists of two convex lenses having focal length 1.5 cm and 5 cm. When an objectt is kept at distance of 1.6 cm from the objective, the final image is virtual and lies at a distance of 25 cm from the eyepiece.
