magnification formula for lenses - 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 ?

Formula: \text{ magnification }= \frac{\text{Average observed width }}{\text{ real width }}

\text{ real width }= \frac{\text{Average observed width }}{\text{ magnification }}

Given that

Average of width of the hair = 3.5 mm

Magnification m = 100

Thickness of the hair = ?

Hence, real thickness of the hair = \frac{3.5}{100} mm

= 0.035 mm
