What Would Happen To The Wave-particle Dualism If Planck’s Constant H=0?

Hi could somebody help me with the question above? I think If Planck’s constant was 0 then the energy in that region which is proportional to the frequency of the light wave would be 0 also. But I think I'm way off! Please help!

E=hf

E=0*f

therefore f= E/0

Dividing by zero destroys the universe
Uh oh!

Sorry I just couldn' resist:)

Dunno honestly don't have a clue . .

De Broglie's wavelength is given by the equation

$$\lambda = \frac{h}{p}$$

where h is Planck's constant and p is the momentum of the particle. What happens to wave-particle duality if h = 0 should be fairly clear now.

uhhhhh ....It isn't to me:uhh:

h = 0 then 0 * (1/p) = ? 0x = ?

If you take the limit as Planck's constant tends to zero then quantum physics reduces to classical physics.

Yes, that means there will no such thing as wave-particle duality. Waves will behave like waves and particles will behave like particles.

Thank you !!

Thanks to all for answering the wave-particle duality question...
