Two Source Interference of Waves – A Level Physics

Published on February 2, 2015 by

Throw stones into a pond and the ripples pass through each other. The same effect of wave interference is also seen with sound, light, and microwaves.

    What is the practical where you use a CD to work out the wavelength of a certain colour of light?

    How does the microwave emitter work if the source is not coherent?

    We need more accurate visual representation of wave interference instead of wrote explanation.Intuitive descriptions is the way to go!!
    Thank you so much again for this!!

    If you cover one of the slits, would the light be less spread out than the light with two slits as it is only being diffracted once whereas with two it is getting diffracted twice?
