Question

Calculate the Brogiles wave lenght associated with an electron with velocity 1. 6×10^6m/s

Answer 1

According to De-Broglie

Wavelength = Planck's constant / Momentum
So,
Wavelength = 6.626*10^-34 / (9.1*10^-31 kg)(6*10^6 m/s)
Planck's constant = 6.626*10^-34 Joules-second
Mass of an electron = 9.1*10^-31 kilograms

Therefore, i suppose wavelength can be calculated further.

Hope this helps you !

Answer 2

According to De-Broglie

Wavelength = Planck's constant / Momentum

So,

Wavelength = 6.626*10^-34 / (9.1*10^-31 kg)(6*10^6 m/s)

Planck's constant = 6.626*10^-34 Joules-second

Mass of an electron = 9.1*10^-31 kilograms

Therefore, i suppose wavelength can be calculated further.
