Question

$C{s}^{+}$ ions impart blue colour to bunsen flame. This is due to the fact that the emitted radiations are of:

• A. high energy
• B. lower frequencies
• C. longer wavelength
• D. zero wave number

Answer 1

The correct option is A high energy

$C{s}^{+}$ ions impart blue colour to Bunsen flame. This is due to the fact that the emitted radiations are of high energy.
Violet color is just before the ultra violet region. This corresponds to high energy. Red colour is just after infra red region. This corresponds to low energy.
