Question

calculate the wavelength of light emitted by the transition of electron from n=3 in the balmer series​

Answer 1

Answer:

The wheels of a car are of diameters 80cm ench. How many complete revolutions does

each wheel make in 10 minutes when the car is travelling at a speed of 66 km per hour.

Answer 2

Explanation:

λ = 656.1 nm

Explanation:

The Balmer series consists of all transitions that end at the ( n=2 ) energy level.

The Rydberg equation gives the wavelength

λ for the transitions:

∣∣∣∣aa1λ

=R(1n21−1n22)aa∣∣∣∣

whereR= the Rydberg constant ( 1.0974×107lm-1 )andn1 and n2 are the numbers of the energy levels such that

n1<n2

For a transition from ( =3 ) to ( n=2 ),1

λ=(1.0974×107lm-1)(14−19)

=(1.0974×107lm-1)×536

=1.524×106lm-1

λ=11.524×106lm-1

=6.561×10-7lm=656.1

This wavelength corresponds to the red line in the hydrogen spectrum.
