MHT CET 2026 Chemistry question
Calculate the de Broglie wavelength of an electron in the first Bohr orbit of a hydrogen atom if the velocity of an electron in the first orbit is [mass of electron = kg plank's constant (h) = J s]
Answer: (A)
Solution
The de Broglie relation is . Substituting, . The denominator is . Therefore \dfrac{6.626×10^{-34}}{2.002×10^{-24}}$ =
