The particle and wave nature of matter are demonstrated in the equation?

A. λ = hc/E
B. λ = h/P
C. λ = c/f
D. λ = 2 d sin θ

Correct Answer:

Option B = λ = h/P

Explanation

I wave-particle duality of matter, the momentum of the sub-atomic particle is given by P = h/λ where h = Planck constant; λ = wave length
=> λ = h/P
