In the depiction of non-coherent light, the photons have different wavelength and so are non-coherent. But even light of same wavelength with phase difference will be non-coherent.
@@EngineeringPhysicsbySanjiv light speed in a vacuum is indeed c, but laser is not just amplified light; it's light where the wavelengths are in phase and im pretty sure it isnt polarised either (won't effect the intensity).

nice video sir
Most welcome..

Sir light speed = laser ???
reply kro kya dono equal he
no.. light speed in free space is c. laser is just amplified light which is unidirectional and intense

Yes.. it is coherent also.. that's absolutely right..
Thanks sir
