Question 359: Dual Nature of Matter and Radiation

Question

The wave number of the last line of the Balmer series in the hydrogen spectrum will be $$\left(ight.$$ Rydberg's cons $$\left.	an t, R=\frac{10^7}{\mathrm{~m}}ight)$$

Accepted Answer

The wave number of the last line of the Balmer series is given by
$$\frac{1}{\lambda}=\frac{R}{4}=\frac{10^7}{4}=25	imes10^5~\mathrm{m^{-1}}$$

Answer

$$16 	imes 10^4 \mathrm{~m}^{-1}$$

Answer

$$8 	imes 10^5 \mathrm{~m}^{-1}$$

Answer

$$36 	imes 10^7 \mathrm{~m}^{-1}$$

Answer

$$25 	imes 10^5 \mathrm{~m}^{-1}$$

Dual Nature of Matter and Radiation

The wave number of the last line of the Balmer series in the hydrogen spectrum will be $\left(\right. Rydberg's cons \left.\tan t, R=\frac{10^7}{\mathrm{~m}}\right)
