    I was all set to answer till you added "2 reasons are required"... it makes this sound suspiciously like a homework problem.

    since this is a homework problem, i can't give you the answer..(you said 2 reasons are required) :rolleyes: but i'll give you some hints lead to the answer

    1. wavelength... in order for a interference exist... what is the restriction on the wavelength?
    2. the phase of the light wave.....
