Questions
A particle moving with kinetic energy E has de Broglie wavelength . If energy is added to its energy, the wavelength become . Value of is:
detailed solution
Correct option is C
de Broglie wavelength=λ=h2E m ⇒ λ ∝ 1E ⇒E∝1λ2If λ becomes half, then E becomes 4 times. ∴Ef=4 Ei ∴ ΔE=Ef− Ei =4 Ei-Ei =3EiTalk to our academic expert!
