In this problem, we need the expression for the de Broglie wavelength.
De Broglie wavelength:
where h is Plank's constant, m is the mass and v is the velocity of the object.
Assume that an electron wave making a standing wave in a hydrogen atom has a wavelength of 1.69 x 10-10 m. If the mass of the electron is 9.11x10-31 kg, what is the velocity of an electron in this orbit according to the de Broglie equation?
a. 2.32e-7 m/s
b. 4.31e-76 m/s
c. 4.31e7 m/s
d. 4.31e6 m/s
e. 1.23e-13 m/s
