please help thank you!

% error in the estimated wavelength. A 1% uncertainty in the spacing between the diffraction minima will yield a You use the interference pattern from a single slit to measure the wavelength of your laser. A 1% systematic error in the distance from the slit to the screen will lead to a % uncertainty in the estimated wavelength.

Answer 1

Formula used B=de Here ß = fringe width A wovelength D = distance between a = width of slét scbeen and slit it systematic error in distance from slit to + > DD x100 = Lula - Clearly D a = D = k t for some constant Sinee Aki = 0 Ab *100 = 48 x100 So, sxx 100 = 1% So percent age essor in estimated wavelength = 1 de
