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.
