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.
