Question

An atom involving three engergy levels emits photons according to these transitions: From the third to the second energy level, it emits a photon whose wavelength is 575 nm, and from the second to the first, it emits a photon of 131nm. Which of the following is true about this atom?

An atom involving three energy levels emits photons according to these transitions: From the third to the second energy level, it emits a photon whose wavelength (M) is 575 nm, and from the second to the first, it emits a photon of 131 nm. Which of the following is true about this atom? a. AE is lower from (3rd) to (2nd) c. AE is higher from (2nd) to (1 st) b. AE is lower from (2nd) to (1 S) d. "a" and "c" are correct

Explanation / Answer

E = h*c/
E and are inversely proportional

so,
greater means lesser E

E is more for seconds to 1st and less for 3rd to 2nd

Answer: d
