Hoe does magnifying power change with change in length of tube for a given microscope ?
Text Solution
Verified by Experts
In case of a microscope, magnifying power `|m| = (v_(0))/(u_(0)) xx (d)/(u_(e))`, where `L = v_(0) + u_(e)` When `L` is increased, `u_(e)` increases as `v_(0)` is fixed `:. |m|` will decrease.

How does magnifying power change with change in length of tube for a given telescope ?
Write the formula for magnifying power and length of tube of an astronomical telescope.
A convex lens of focal length 5cm is used as a simple microscope. What is the magnifying power, if final image is formed at the distance of distinct vision i.e. 25 cm ? If it is used as an eyepiece in a compound microscope with objective of magnifying power 40, what is the magnifying power of the compound microscope ?
The magnifying power of simple microscope is
Magnifying power of a microscope depends on
The magnifying power of a compound microscope is high if
The focal lengths of the objective and eye - lens of a microscope are 1cm and 5 cm respectively. If the magnifying power for the relaxed eye is 45 , then the length of the tube is
