Question

As a superhero, it is critical that your true identity remain secret. While cleaning the house, your bald butler finds a hair that does not belong to you and clearly does not belong to him either. You decide to use your physics knowledge to investigate. Your butler holds the hair 13.2 m from the wall. You set your laser gun to emit a 625 nm wavelength beam of light. You 9-7 2 pts order minima being located at 2 cm from the axis, Determine the width of the hair so that you can begin searching for the culprit. micrometers ( ± 1 micrometers)

Explanation / Answer

Distance of 2nd minima in a single slit diffraction from the axis = 2 x distance between the source & screen x wavelength/ slit width

so, 2 x 10-2 = 2x 13.2 x 625 x 10-9/ width of hair

so, width of hair = 2x 13.2 x 625 x 10-9/ 2 x 10-2 = 825 micrometers

all the best in the course work
