A free hydrogen atom after absorbing a photon of wavelength λₐ gets excited from the state n = 1 to the state n = 4. Immediately after that the electron jumps to n = m state by emitting a photon of wavelength λₑ. Let the change in momentum of atom due to the absorption and the emission are Δpₐ and Δpₑ, respectively. If λₐ/λₑ = 1/5, which of the option(s) is/are correct? [Use hc = 1242 eV nm; 1 nm = 10⁻⁹ m, h and c are Planck’s constant and speed of light, respectively]
