If Planck's constant ($h$) were zero, what would be the consequence for physical behavior?

Answer

Everything would conform perfectly to classical mechanics.

The text specifies that if $h$ were zero, the wave aspect would vanish entirely, and physics would align perfectly with classical mechanics.

If Planck's constant ($h$) were zero, what would be the consequence for physical behavior?
