Planck's constant increases None of the above occurs as the energy of a photon increases. Short Answer/Problems 36. (2 pts) Why do atoms only emit certain wavelengths of light when they are excited? (Why do line spectra exist?)

Answer 1

Note Book Date Puo Q-31) TEA 1012 19oo 4960 Ito IES 6270 22,200 Octet complete More energy is required to lose an elections from estable configuration (Sudden increase in energy) e correct option 2222 a 15 35 36 (1) till in=3 l= p-orbital is. me = -1, , + mg = + 2,4 = 1

2.317 m-3, -1, m correct option ② , mets ma - I to tl. el, o,+ ve 3 values - Correct option d 134) Electronic configuration for oxygen 0- a spell correct option @ By Planck quantum theory s frequency of photon of of the frequerey decreases, the energy of - a photch decreases & vice-versa correct option: -

Note Book Dato -36) Because the electrons revolve around the nudeus in certain energy levels, called orbits ve energy is fin . When an electron atrops from a highe orbit to lower orbit, the energy is em in form of phaton, herce specific wavelength are admitted.
