The spectrum of an oil flame is an example for
1 Line emission spectrum
2 Continuous emission spectrum
3 Line absorption spectrum
4 Band emission spectrum
Explanation:
The spectrum of an oil flame is a continuous emission spectrum over a wide band ranging from ultraviolet to infrared. \(\frac{{\lambda '}}{\lambda } = 3\) or \(\lambda ' = 3\lambda \)
PHXII12:ATOMS

An electron jumps from the 4\(th\) orbit to 2\(nd\) orbit of the hydrogen atom. Give, Rydberg’s constant \(R = {10^7}{m^{ - 1}}\), the frequency in hertz of emitted radiation will be

Maximum energy is released during which of the following transitions?
1 \(n = 1\,\,{\rm{to}}\,\,n = 2\)
2 \(n = 2\,\,{\rm{to}}\,\,n = 6\)
3 \(n = 2\,\,{\rm{to}}\,\,n = 1\)
4 \(n = 6\,\,{\rm{to}}\,\,n = 2\)
Explanation:
When transition is from upper state to lower state, the energy is evolved. In option (3), \(E = Rch\left( {\frac{1}{{{1^2}}} - \frac{1}{{{2^2}}}} \right) = \frac{3}{4}Rch\) In option (4),\(E = Rch\left( {\frac{1}{{{2^2}}} - \frac{1}{{{6^2}}}} \right) = \frac{2}{9}Rch\) Thus, maximum energy is evolved in option (3), When transition takes place between \(n = 2\) to \(n = 1\).
