Question

7. Calculate the wavelength of an electron moving with a velocity of 2.05 x 107 m/s.
options are::::

(a) 3.55 x 10-11m (b) 4.05 x 10-10m (c) 5.55 x10-11m (d) 7.05 x10-11m

​

Answer 1

Answer:

3.55*10^-11m

Explanation:

The wavelength of electron is obtained from de-broglie equation

lambda=h/mv

= (6.626*10^-34 Js) / (9.11*10^-31 kg) *(2.05*10^7 m/s)

Answer 2

Answer:

thanks for the points thanks
