Question

Q262) Two particles A and B are in motion. If the wavelength associated with particle A is 5 × 10^{–8} m ; calculate the
wavelength associated with particle B if its momentum is half of A.

Q262) Two particles A and B are in motion. If the wavelength associated with particle A is 5 × 10

SOLUTION

λ ∝ 1/λ

λ_{A} = 5 × 10^{–8}m
∴ λ_{B} = 10^{–7}m
∴ λ_{B} = 10^{–5}cm

Answer:(b)
