Question

What is the wavelength associated with 0.113kg ball traveling with velocity of 43 m/s?

Answer 1

Wavelength = 1.36 * 10^{-34} meters

Step-by-step explanation:

Given the following data;

Mass = 0.113 kg

Velocity = 43 m/s

To find the wavelength, we would use the De Broglie's wave equation.

Mathematically, it is given by the formula;

`Wavelength = \frac {h}{mv}`

Where;

h represents Planck’s constant.

m represents the mass of the particle.

v represents the velocity of the particle.

We know that Planck’s constant = 6.6262 * 10^{-34} Js

Substituting into the formula, we have;

`Wavelength = \frac {6.6262 * 10^(-34)}{0.113*43}`

`Wavelength = \frac {6.6262 * 10^(-34)}{4.859}`

Wavelength = 1.36 * 10^{-34} meters
