If you assume that light travels in waves, and the waves can interfere, then the math is easy. Just do the math and get the answers.

Here’s a link that gives a condensed explanation.

As you increase the slit separation, the separation between bright bands decreases.

Green light is what I used in the example! What you may be asking: as wavelength increases, the separation between bands increases.

i want to ask u…
1) if the double slits is separation of d is increases what would happen to the separation distance between two onsecutive bright bands???
2) if we use laser light green what wuold happen to the separation distance between two consecutive bright bands???

If time could be thought of as a separate dimension(s) might it be possible for a thing to exist almost entirely in time (a wave) and intersect only very briefly with space at singular points (particles)? The science is beyond me. No less curious, all I can do is look beyond the science.

Could you be a bit more specific? I’m not sure what you mean by the “total number” of maximas. In principle, there are an infinite number spread out across the measurement plane, with a certain density of maximas per unit length.

i cannot understand how the total no. of maximas are counted…………..i alwaz get confused ………..please tell me how to do that………

Hmm… haven’t heard anything about such an explanation; I’ll have to look into it!

Seems I’ve seen reference to Freznel and Huygens commenting on a background field being a possible explanation of the double slit results. Any validity to this theory?

This is very clear,i can understad simple.thank you
