Calculate the wavelength of an electron mass 9.1*10^-31kg moving with a velocity of 2.0*10^6m/s (h=6.63*10^-34Js) (Hint: De Broglie's wavelength)

Wavelength,

Explanation:

We have,

Velocity an electron is

Mass of an electron is

It is required to find the wavelength of electron. The De-Broglie wavelength of an electron is given by :

h is Planck's constant

So, the wavelength of an electron is .

"i have always loved contemporary art and made it a general goal to work within the field. after a few nonprofit internships at museums and galleries, i decided to try the for-profit art world and was offered a job as the ad assistant at the magazine. i much prefer the pace of the for-profit art community and have stayed with the company for three years, with a promotion to an account manager last spring."

i just did this and got a 100.
