(b)
Answer to Problem 1P
The three lines are in ultraviolet region.
Explanation of Solution
The wavelength corresponds to the first three lines is
The electromagnetic spectrum starts from radio waves to gamma waves. In between the visible light with wavelength
The above lines would have lesser wave length compared to the visible and is greater than X-ray wave.
Thus, the above lines would falls under the region of ultraviolet.
Conclusion:
Therefore, the three lines are in ultraviolet region.

- When the absorption spectrum of hydrogen at room temperature is analyzed, absorption lines for the Lyman series are found, but none are found for the Balmer series. What does this tell us about the energy state of most hydrogen atoms at room temperature?arrow_forwardThe Balmer series for hydrogen was discovered before either the Lyman or the Paschen series. Why?arrow_forwardSuppose an electron in a hydrogen atom makes a transition from the (n+1) th orbit to the nth orbit. Is the wavelength of the emitted photon longer for larger values of n, or for smaller values of n?arrow_forward
- When a hydrogen atom is in its ground state, what are the shortest and longest wavelengths of the photons it can absorb without being ionized?arrow_forwardCalculate the wavelength of the first line in the Lyman series and show that this line lies in the ultraviolet part of the spectrum.arrow_forwardDo the Balmer series and the Lyman series overlap? Why? Why not? (Hint: calculate the shortest Balmer line and the longest Lyman line.)arrow_forward
