A student measures the thickness of a human hair by looking at it through a microscope of magnification 100. He makes 20 observations and finds that the average width of the hair in the field of view of the microscope is 3.5 mm. What is the estimate on the thickness of hair?

0.035 mm
Given:
The size of Magnification (m) = 100
Number of observations made = 20 observations
The field view of the microscope (Thickness) = 3.5 mm
To Find:
The thickness of the hair
Formula used to find magnification:
Magnification = Thickness of image of hair / Real Thickness of hair
Calculating:
Substituting the values in the formula for magnification:
= 3.55 / 100
= 0.035 mm
Therefore, the thickness of hair is 0.035 Millimetres.

Given,
➡️The size of
magnification (m) = 100
➡️ Number of observations = 20
➡️The field view = 3.5mm(Thickness)
To Find:-
The thickness of hair.
Calculations:-
Magnification = Thickness of image /Real thickness
=3.55/100
=0.035mm

Magnification:- Magnification is the increase in size of an image produced by an optical system compared to the true size.
- "M" denotes magnification.
- When this number is less than one, it refers to a reduction in size, sometimes called minification or de-magnification.
