State Abbe's condition for the least distance between two objects so that they are just resolved [when they are viewed through a microscope].

State Rayleight.s criterion for two close lying points on an object when they are: just resolved.

What is the best position of the eye for viewing an object through a microscope?

What is the best position for eye viewing an object through microscope ?

In a compound microscope, the distance between objective lens and eye lens is.

The reciprocal of the smalles angular separation between two distance object, so that they appear just separated is

An object appears ______ when viewed through a concave lens.

The vertical angle subtended by two points on a glass block at the objective of a microscope is 20^@ .Calculate the minimum distance between the points if they are just resolved when illuminated by light of wavelength 600 nm. What is the increase in resolving power of the instrument if the objective is immersed in oil of refractive index 1.5?

The smallest angular or linear separation between the two point objects at which they appear to be just resolved is known as

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 )
