If mass and velocity are unknown when using de Broglie's wavelength formula, what alternative value must we have to successfully determine the wavelength

The particle momentum, p

Explanation:

A particle's de Broglie's wavelength is an indication of the scale in length where the particle's wave-like properties are important. The symbol of de Broglie wavelength is λ or given as follows;

The de Broglie's wavelength formula is given as follows;

Where;

λ = The wavelength of the particle in meters

v = The velocity of the particle in meters/seconds

m = The mass of the particle in kilograms

p = The momentum of the particle

h = Planck's constant = 6.626 × 10⁻³⁴ J/Hz

Therefore, the alternative value that we must have to successfully determine the wavelength if the mass and velocity are unknown, is the momentum, p of the particle.

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

radiation

explanation:

heat is transmitted by radiation
