An electron is moving at a speed of c/100. find its debroglie wavelength and frequency. neglect relativistic effects.

DeBroglie wavelength is

Frequency is

Explanation:

Mass of electron = 9.10938356 × 10⁻³¹ kg

Planck's constant = h = 6.626 × 10⁻³⁴ m²kg/s

Speed of light = c = 3×10⁸ m/s

DeBroglie wavelength is

Frequency is

Explanation:

The expression for the deBroglie wavelength is:

Where,

is the deBroglie wavelength

h is Plank's constant having value

m is the mass of electron having value

v is the speed of electron.

Given that v = c / 100

Where, c is the speed of light having value

Thus, v =

Applying in the equation as:

Also,

So,

volume: 22

density: 7.04
