Question

Two particles A and B are in motion. If the wavelength associated with particle A is 5×108m. Calculated the wavelength (in ˚A) associated with particle B if its momentum is half of A.

Solution

  • One wavelength equals the distance between two successive wave crests or troughs.
  • We know De-Broglies wavelength is given by,
λ=hp, where h is Planck's constant and p is momentum
Given,
λA=5×108m and momentum of B is half of momentum of A.
So,
λAλB=0.5
λB=2×λA
λB=10×108=1000Angstrom
