if the value of planck's constant is taken as 6.63 * 10^-34 Js, velocity as 6 * 10^6 m/s and that of mass of electron as 9.11 * 10^-31, find the wavelength of that electron using the De Brogile Wavelength.

Answer:
1.45×10×10×10×10×10×10m/s
Explanation:
the deBroglie wavelenght of an electron is equal to 103 times the wavelength of a photon of frequency 6×1014Hz, then the speed of electron is equal to : (Speed of light = 3×108m/s Planck's constant = 6.63×1034J . Mass of electron = 9.11031kg)
