(Answers to odd-numbered Conceptual Questions can be found in the back of the book.)

(a) Is there an upper limit to the wavelength of lines in. the spectrum of hydrogen? Explain. (b) Is there a lower limit? Explain.

Solution 8CQ

Step 1 of 3</p>

Here, we have to calculate the three longest wavelengths in Lyman series.

The equation for the wave number,

Where, - Rydberg constant

- ‘n’ value corresponding to the series

- the ‘n’ value corresponding to the state

a)

Step 2 of 3</p>

From the equation, it is clear that, the

Therefore, we can say that, there is no upper limit for wavelength in the hydrogen spectrum.
