Question

A laboratory experiment produces a double-slit interference pattern on a screen. The point on the screen marked with a white dot (on a DARK fringe this time) is how much farther from the left slit than from the right slit

Answer 1

Explanation:

Diffraction is a characteristic phenomenon for waves, and is based on their variance to find an obstacle or a crack. The diffraction and interference are inseparable phenomena, which are so harder to identify. Since diffraction is a specific type of interference.

if the point are in the order 2, and

the equation is d×senx=mL y at m=2
