Question

If ∝ particle and proton have same momentum, the ratio of de Broglie wavelength of ∝-particle and proton is……. 

(A) (1/4)

(B) (1/2) 

(C) 1 

(D) 2

Answer 1

The correct option is (C) 1.

Explanation:

we know, 

λ = (h/p) 

Given is momentum = p is same. 

Hence λ = constant

 ∴ (λ_∝ / λ_p) = 1
