Question

What does the de Broglie relation λ = h/mv describe?
Options
A The energy of a photon in terms of its frequency
B The wavelength of a moving particle in terms of its mass and velocity
Correct Answer
C The momentum of an electron in a circular orbit
D The threshold frequency for the photoelectric effect
Correct Answer

Option B is the correct answer.

Detailed Explanation

The de Broglie relation, λ = h/mv, expresses the wavelength (λ) of a moving particle in terms of Planck's constant (h) and the particle's momentum (mv). This equation demonstrates that all moving particles have wave-like properties, with the wavelength inversely proportional to momentum.

Hint

Identify the variables in the equation: λ represents wavelength, h is Planck's constant, m is mass, and v is velocity.
