 P: 391 Hi, Why are mass and wavelength are inversely proportional?
 P: 674 Are you refering to de Broglie's matter waves? As Hawking said, physics' job is to ask how. It's philosophy's business to ask why. But briefly, interference effects can be observed with electron beams, but not with marbles, and the shorter the wavelength of anything, the more it acts like a particle.
 P: 391 ok I change my question .."how are mass and wavelength are inversely proportional? "
 HW Helper P: 2,155 Relation between mass and wavelength $$\lambda = \frac{h}{p}$$
 P: 391 Looks very helpful but what is "h" and what is "p" ?
 P: 3,014 h is a fundamental constant of nature and $$p = \frac{m \, v}{\sqrt{1 - v^{2}/c^{2}}}$$ is the momentum of a particle with mass m moving at speed v and c is the limit speed with which any interaction can be transmitted and is another fundamental constant of nature.
 P: 391 oh ok got it Thanks very much
