Physics, asked by muhjubhaali, 1 year ago

power of magnifyin glass is given by

divyansh101dabral: if focal length is 2m , them power is 1/2=0.5 dioptre

divyansh101dabral: magnification is image length/object length

divyansh101dabral: hope it helps

muhjubhaali: can you write that mathematically

divyansh101dabral: i have done that

divyansh101dabral: m=HI/HO

divyansh101dabral: meaning magnification is height of image /height of object

divyansh101dabral: P=1/f

divyansh101dabral: where p is power in dioptre and f is focal length in metres

divyansh101dabral: is this ok

The distance the focal point is from the surface of a lens is called the focal length of a lens, and is important when determining the magnifying power of devices like magnifying glasses. Magnifying power is how much larger a given lens can make an image appear.

muhjubhaali: mathematically please

Answer:

Explanation:

A magnifying glass (called a hand lens in laboratory contexts) is a convex lens that is used to produce a magnified image of an object.

Calculating Magnification Power. Magnification power is calculated by dividing the focal length of the scanning object (lens) by the focal length of the eyepiece. A 1x magnification power is a 100 percent increase in the magnified object's size For example, a 1-inch object at 1x would appear to be 2 inches.
