Question

the energy between two energy levels in CO2 laser is 0.117eV,the wavelength of the radiation will be​

Answer 1

Answer:

Given E= 0.275 eV = 0.275 *1.6*10-19 J = 0.44 * 10 -19 J ( Converting eV into J , as 1eV = 1.6 * 10 -19 J)

Now using E = h* frequency

Frequency = 0.44* 10-19 / h ( Where h= Planks Constant in JS) Use h= 6.62 * 10 -34 Js

Frequency = 0.44* 10-19/ 6.62* 10-34 Hz = 0.0664 * 1015Hz = 6.64 * 10 13 Hz
