wavelength

[Sisam Bhattarai 2C]

What is the relationship between mass and wavelength size? Is it direct or indirect?

Wavelength is inversely proportionate to momentum. Since momentum is p = mv, wavelength is inversely proportionate to mass as well.

Hi,
I believe that mass and wavelength are essentially inversely proportional. The equation for wavelength, lambda, can be lambda = h / momentum. Momentum is (mass x velocity). If you plug this in for momentum in the first equation, you get lambda = h / (mass x velocity). The smaller mass is, the bigger your lambda, or wavelength.

Hi! When looking at De Broglie's equation, you can see that if the mass increases, the wavelength decreases. Therefore, wavelength and mass have an inversely proportional relationship.
