PhysicsMedium145×since 2002Q6583The de Broglie wavelength of an electron having kinetic energy E\mathrm{E}E is λ\lambdaλ. If the kinetic energy of electron becomes E4\frac{E}{4}4E, then its de-Broglie wavelength will be :A2λ\sqrt{2} \lambda2λB2λ2 \lambda2λCλ2\frac{\lambda}{2}2λDλ2\frac{\lambda}{\sqrt{2}}2λCheck answerSkip
