Question

Young's double slit experiment breaks a single light beam into two sources. Would the same pattern be obtained if two lasers of the same wavelength were side by side, the same distance from each other as the slit separation?

Yes, because the laser light has patterns that don't work together.

No, because the laser light has tiny inconsistencies between them, causing this idea to fail.

No, because the laser light isn't from the same source.

Yes, because the light from the two lasers will interfere when the waves overlap.

Explanation / Answer

No, because the laser light has tiny inconsistencies between them, causing this idea to fail.

even the lasers are from different sources they still have same wavelengths. They may be or may not coherent and they may be or may not be in same phase.

even if they are in same phase it will not form the same pattern
