The de-Broglie wavelength of an electron having kinetic energy is,
[Use mass of electron ]
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
Apply the de-Broglie wave equation, λ=hp to solve for the wavelength of the moving electron. Recall the proper formula of wavelength in terms of kinetic energy, λ=h2K.E.m, given, K.E.=100 eV=100×1.6×10-19 J, it means,…
