If the deBroglie wavelenght of an of a photon of frequency `6xx 10 ^4`Hz ,then the speed of electron is equal to (Speed of light `=3 xx 10^8 m//s `
Planck's constant `=6.63 xx 10 ^(-34)` J s
Mass of electron `=9.1 xx 10 ^(-31)` kg

If the deBroglie wavelenght of an electron is equal to 10^-3 times the wavelength of a photon of frequency 6xx 10 ^4 Hz ,then the speed of electron is equal to (Speed of light =3 xx 10^8 m//s Planck's constant =6.63 xx 10 ^(-34) J s Mass of electron =9.1 xx 10 ^(-31) kg

If the deBroglie wavelenght of an electron is equal to 10^-3 times the wavelenght of a photon of frequency 6xx 10 ^14 Hz ,then the calculate speed of electrone. Speed of light =3 xx 10^8 m//s Planck's constant =6.63 xx 10 ^(-34) J s Mass of electron =9.1 xx 10 ^(-31) kg

If the deBroglie wavelength of an electron is equal to 10^(-3) times the wavelength of a photon of frequency 6xx10^(-14)Hz then the speed (in m/s) of electron is equal to: (Speed of light =3xx10^(8)m//s) Planck's constant =6.63xx10^(-34)J.s Mass of electron =9.1xx10^(-31)kg)
