If h is planck’s constant and λ is wavelength, h/λ has dimensions of

If h is planck’s constant and λ is wavelength, h/λ has dimensions of

Options

(a) momentum
(b) energy
(c) mass
(d) velocity

Correct Answer:

momentum

Explanation:

Dimension of Planck’s constant = ML²T⁻¹

Dimension for wavelength  = L

h/λ = MLT⁻¹

Which is same as that of dimension of momentum
