A guitar string is 70 cm long and has a mass of 3.6g. The distance form the bridge to the support post is L=60cm, and the string is under a tension of 502 N. What are the frequencies of the fundamental?

The atoms in a nickel crystal vibrate as harmonic oscillators with an angular frequency of 2.3 × 1013 rad/s. the mass of a nickel atom is 9.75 × 10-26 kg. what is the difference in energy between adjacent vibrational energy levels of nickel? (h = 6.626 × 10-34 j • s, , 1 ev = 1.60 × 10-19 j)
