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=15 , which of the option (s) is /are correct ?[Use hc=1242eVnm;1nm=10−9m,h, and c are Planck’s constant and speed of light, respectively]
