To determine the wavelength of He-Ne laser light using single slit diffraction
1. In flatness testing with interferometry, if surfaces are perfectly wrung. Then which option is correct regarding fringe pattern?
2. Which type of fringe is formed, if a path difference of λ/2 is observed in an interference pattern?
3. What is the purpose of conducting a single-slit experiment to determine the wavelength of HeNe laser light?
4.Which parameter primarily affects the width of the central maximum in the diffraction pattern obtained from a single slit?
5.In a single-slit diffraction pattern, why do minima occur?
