Dual Nature of Radiation question

2020 · 6 Sep · Shift 1 · Q57

JEE MainPhysicsDual Nature of RadiationMCQ+4 / −1
An electron, a doubly ionized helium ion (He++) and a proton are having the same kinetic energy. The relation between their respective de-Broglie wavelengths λ\lambdaλ e, λ\lambdaλ He++ and λ\lambdaλ p is :
  1. A
    λ\lambdaλ e > λ\lambdaλ He++ > λ\lambdaλ p
  2. B
    λ\lambdaλ e < λ\lambdaλ p < λ\lambdaλ He++
  3. C
    λ\lambdaλ e > λ\lambdaλ p > λ\lambdaλ He++
  4. D
    λ\lambdaλ e < λ\lambdaλ He++ = λ\lambdaλ p
