Homework Help: Which colour of light is diffracted most through diffractional grating?

  1. Nov 9, 2007 #1
    the condition for a maximum is ;

    dsinθ=nλ

    let d and n be constant then θ (angle) increases as λ(wavelength) increases. So the θ will be the greatest for the highest value of λ ..........that implies the frequency is lowest.
    So I think light of lower frequency are diffracted much ....Am I right?

    For a given order of diffraction (n), that is true.
