[QUOTE="coconut62, post: 4541177, member: 463927"] [h2]Homework Statement [/h2] The question is regarding Young's double slit experiment. "Describe the effect, if any, on the separation and on the maximum brightness of the fringes when the following changes are made. ... ... 2) The wavelength λ is increased to 1.5λ, keeping a and D constant. Separation: Maximum brightness: [h2]Homework Equations[/h2] λ=ax/D [h2]The Attempt at a Solution[/h2] My answer: Separation: Increases by 1.5 times Maximum brightness: Same [COLOR="Red"](Wrong, answer: less bright)[/COLOR] Why would the change in wavelength alter the brightness of the fringes?
