Find the de Broglie wavelength of electrons moving with a speed of `7 xx 10^(6) ms^(-1)`

(b) Calculate de Broglie wavelength for an electron moving with a speed of 10^(6)" m s"^(-1) .

What will be de Broglie's wavelength of an electron moving with a velocity of 1.2 xx 10^(5) ms^(-1) ?

How fast does a proton have to be moving with order to have the same de-Broglie wavelength as an electron that is moving with a speed of 5.5xx10^(6)ms^(-1) ? Mass of proton =1.67xx10^(-27)kg .

The de Broglie wavelength of an electron moving with a velocity of 1.5xx10^(8)ms^(-1) is equal to that of a photon find the ratio of the kinetic energy of the photon to that of the electron.

The de-Broglie wavelength of an electron moving with a velocity 1.5 xx 10^(8)ms^(-1) is equal to that of a photon. The ratio of the kinetic energy of the electron to that of the photon is:

The de-Broglie wavelength of an electron moving with a velocity 1.5xx10^(8) ms^(-1) is equal to that of a photon. Caculate the ratio of the kinetic energy of the electron to that of photon.
