The rate of formation of ozone depends on the flux of:
Correct answer: B. Ultra violet radiation
- A. visible radiation
- B. Ultra violet radiation
- C. Infrared radiation
- D. Gamma rays
Explanation
Ultraviolet radiation supplies the energy needed to split oxygen molecules into oxygen atoms, which then combine with O2 to form ozone, O3. Visible and infrared radiation do not normally provide the required photochemical energy for ozone formation. Students may choose gamma rays because they are more energetic, but natural ozone formation in the upper atmosphere is driven mainly by ultraviolet radiation.

About Spectrum of Hydrogen
The hydrogen spectrum consists of discrete emission lines produced when electrons fall between quantised energy levels and release photons. Questions use the Rydberg equation, photon energy and wavelength, and identify the Lyman, Balmer, Paschen, Brackett and Pfund series, which differ from continuous spectra.
