Which of the following is the principle of Flame emission photometers?
A. Radiation is absorbed by non-excited atoms in vapour state and are excited to higher states
B. Medium absorbs radiation and transmitted radiation is measured
C. Colour and wavelength of the flame is measured
D. Only wavelength of the flame is measured
Answer:C
