Question

If a photon and an electron have the same momentum:

• Either may have the greater wavelength, depending upon the value of the momentum.
• The electron has the greater wavelength.
• The photon has the greater wavelength
• They have the same wavelength.

Answer 1

When a photon and an electron have the same momentum, they have different wavelengths.

Step-by-step explanation:

When a photon and an electron have the same momentum, they have different wavelengths. The photon has a wavelength related to its momentum by λ = h/p, where h is the Planck constant. The electron, on the other hand, has a de Broglie wavelength related to its momentum by λ = h/mv, where m is the mass of the electron and v is its velocity.
