1.	Using the postulates of Bohr’s model of hydrogen atom, obtain anexpression for the frequency of radiation emitted when the atom makes a transition from the higher energy state with quantum number ni to thelower energy state with quantum number nf. Where nf is smaller than ni.
Answer» For a cantilevered beam, the boundary conditions are as follows: w(0)=0 . This boundary condition says that the base of the beam (at the wall) does not EXPERIENCE any deflection. w'(0)=0 . We also assume that the beam at the wall is horizontal, so that the derivative of the deflection function is zero at that point. w''(L)=0 . This boundary condition MODELS the assumption that there is no bending moment at the free end of the cantilever. w'''(L)=0 . This boundary condition models the assumption that there is no shearing FORCE acting at the free end of the beam. If a concentrated force is applied to the free end of the beam (for EXAMPLE, a weight of mass m is hung on the free end), then this induces a shear on the end of the beam. Consequently, the the fourth boundary condition is no longer valid, and is typically replaced by the condition w'''(L)= -mg where g is the acceleration due to gravity (approximately 9.8 m/s^2). We note that we could actually use this boundary condition all the time, since if m=0 , it reduces to the previous case.

For a cantilevered beam, the boundary conditions are as follows:

w(0)=0 . This boundary condition says that the base of the beam (at the wall) does not EXPERIENCE any deflection.

w'(0)=0 . We also assume that the beam at the wall is horizontal, so that the derivative of the deflection function is zero at that point.

w''(L)=0 . This boundary condition MODELS the assumption that there is no bending moment at the free end of the cantilever.

w'''(L)=0 . This boundary condition models the assumption that there is no shearing FORCE acting at the free end of the beam.

If a concentrated force is applied to the free end of the beam (for EXAMPLE, a weight of mass m is hung on the free end), then this induces a shear on the end of the beam. Consequently, the the fourth boundary condition is no longer valid, and is typically replaced by the condition

w'''(L)= -mg

where g is the acceleration due to gravity (approximately 9.8 m/s^2). We note that we could actually use this boundary condition all the time, since if m=0 , it reduces to the previous case.

Using the postulates of Bohr’s model of hydrogen atom, obtain anexpression for the frequency of radiation emitted when the atom makes a transition from the higher energy state with quantum number ni to thelower energy state with quantum number nf. Where nf is smaller than ni.
