Assuming that the smallest measurable wavelength in an experiment is 0.430 fm , what is the maximum mass of an object traveling at 885 m⋅s−1 for which the de broglie wavelength is observable?

- The maximum mass of the object is .

Solution:- The equation for de-Broglie wavelength is:

where, h is planck's constant, m is the mass and v is the velocity.

Given wavelength is 0.430 fm. fm stands for femtometer. let's convert it to meter.

=

velocity is given as . Let's plug in the values in the equation:

(at denominator the first m stands for mass and the second m is the unit of length that stands for meter)

We know that,

So,

So, the maximum mass of the object is .

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
