Dual Nature of Radiation question

2019 · 9 Apr · Shift 2 · Q62

JEE MainPhysicsDual Nature of RadiationMCQ+4 / −1
A particle 'P' is formed due to a completely inelastic collision of particles 'x' and 'y' having de-Broglie wavelengths 'λ\lambdaλ x' and 'λ\lambdaλ y' respectively. If x and y were moving in opposite directions, then the de-Broglie wavelength of 'P' is :-
  1. A
    λx−λy{\lambda _x} - {\lambda _y}λx​−λy​
  2. B
    λxλy∣λx−λy∣{{{\lambda _x}{\lambda _y}} \over {\left| {{\lambda _x} - {\lambda _y}} \right|}}∣λx​−λy​∣λx​λy​​
  3. C
    λx+λy{\lambda _x} + {\lambda _y}λx​+λy​
  4. D
    λxλyλx+λy{{{\lambda _x}{\lambda _y}} \over {{\lambda _x} + {\lambda _y}}}λx​+λy​λx​λy​​
