Magnifying power of a Simple Microscope ​

Answer 1

$\boxed{ \underline{\bf\large{ \star \: Magnifying \: power \: of \: a \: Simple \: Microscope \: \star \: \: }}}$

On the eye angle created by the simple microscope and keeping the object at a minimum distance of clear vision, the object's visual angle of the eye on the eye is called the magnifying capacity of a simple microscope.

$\bf \: If \: the \: object's \: reflection \: is \: the \: lowest \: \\ \bf \: distance \: of \: the \: visible \: vision \: D \: \\ \bf \: and \: the \: focus \: distance \: of \: the \: lens \: is \: f$

The magnifying capacity of simple microscope

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \huge{ \boxed{ \bf \: M = 1 + \frac{D}{f} }}$

$\bf \: If \: an \: object \: is \: at \: the \: distance \: of \: the \: lens \: \\ \bf \: at \: a \: distance \: , \: Then \: the \: big \: \\ \bf \: image \: of \: the \: object \: is \: made \: on \: the \: \\ \bf \: eternal ".$

In this state of the eye, ie tension-free But the magnification capacity of the microscope decreases.

Therefore, the magnification ability of simple microscope for a blind eye

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \huge{ \boxed{ \bf \: M = \frac{D}{f} }}$

is evident from the above sources that the value of the focus distance will be as low as the value of the magnification capacity, but the very least the focus distance is the lens thick, through which the image formed If the defect arises, the compound microscope is used instead of the simple microscope to obtain more magnification capacity .
