What is the velocity of an electron that has a de broglie wavelength approximately the length of a chemical bond? assume this length to be 1.2×10−10 m. (the mass of an electron is 9.11×10−31kg.)

velocity

Explanation:

We have given mass of electron

De broglie wavelength is given as

According to de broglie hypothesis , here h is plank's constant , m is mass of electron and v is velocity of electron

Value of plank's constant

Putting all these value in wavelength formula

80cm/s.

24cm/s.

53.3cm/s.
