Unformatted text preview: 1. The condition for a minimum of a singleslit diï¬€raction pattern is a sin Î¸ = mÎ» where a is the slit width, Î» is the wavelength, and m is an integer. The angle Î¸ is measured from the forward direction, so for the situation described in the problem, it is 0.60â—¦ for m = 1. Thus a= mÎ» 633 Ã— 10âˆ’9 m = 6.04 Ã— 10âˆ’5 m . = sin Î¸ sin 0.60â—¦ ...
