The de Broglie wavelength of a photon is twice the de Broglie wavelength of an electron. The speed of the electron is vₑ=c/100 A)The speed of the photon is vᵧ = c/200 , and its de Broglie wavelength is λᵧ=h/ mₑc. B) The speed of the photon is vᵧ = c/50 , and its de Broglie wavelength is λᵧ=h/ mₑc . C)The speed of the photon is vᵧ = c/100, and its de Broglie wavelength is λᵧ=h/ 2mₑc. D) The speed of the photon is vᵧ = c/100 , and its de Broglie wavelength is λᵧ=h/ mₑc
