Photon has no mass.So when we apply Uncertainity principle to photon(adsbygoogle = window.adsbygoogle || []).push({});

position*velocity*mass=greater than plancks constant

So when we use mass as null,the equation implies that 0<h.

That is h is negative.But h is positive.

Please explain me this.
