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
