Answer:
Solution :
We know that
Number of waves =Circumference of electron orbitWavelength=2πrλ
But λ=hmυ
∴ Number of waves =2πr×mυh=2πh(mυr)
Thus angular momentum for Bohr's third orbit is given as :
mυr=nh2π=3h2π
Substituting the value of mυ r in expression (i),
Thus, number of waves =2πh×3h2π=3
Thus , the number of waves in Bohr's third orbit =3.
