In a compound microscope, if the objective produces an image and the eyepiece produces an image , then choose correct statement:

How can you differentiate between a compound microscope and a telescope just by looking at it?

Final image obtained from a compound microscope is-

Final image obtained from a compound microscope is -

A compound microscope consists of an objective lens with focal length the magnification will be

The objective lens and eye piece lens of a compound microscope have focal lengths 1.5 cm and 5 cm respectively. The object is placed at a distance 1.8 cm. What is its magnification? ( Take the least distance of distinct vision = 24 cm)

A microscope is having an objective of focal length and eyepiece of focal length . If tube length is and the image is formed at the least distance of distinct vision, what is the magnification produced by the microscope? (Take )

A compound microscope has an eye piece of focal length 10 cm and an objective of focal length of 4 cm. Calculate the magnification, if an object is kept at a distance of 5 cm from the objective then final image is formed at the least distance of distinct vision
