oo cricket 11:38 PM ( 0 96% + Done 7 of 8 Problem 14 (s.00 pts) Generally speaking, the speed of sound will be higher on a string that is A) More dense and and at a lower Ssion B) Less dense and at a lower semsio C) More demsc and at higher tension yssdmse and higher tenice Problem is (s.oo pts): first four eorgylevelsfor an electron inlydng 1d emit a photon with the highet etmp? (there Ofthe The energy diagram shows listed below, which of these ore not listed.) m-3 to - Problem 16 (soo pts): Ara electron changes energy states from higher energy to a lower megy stat following correctly expresses the wavelength of light emitsed in this transition? Wh of hf he Ea- Ei he

Explanation / Answer

14) option d is correct.

velocity of sound is giving by v = sqrt(T/u)

15) option E is correct

. transition from n=4 to 1 releases maximum energy

16) delta E = hc/lambda lambda = hc / delta E

option b is correct
