Q1.

A string is stretched and fixed at both ends, 202 cm apart. If the density of the string is 0.012 g/cm, and its tension is 676 N, what is the wavelength (in cm) of the first harmonic?

Q2.

A string is stretched and fixed at both ends, 198 cm apart. If the density of the string is 0.024 g/cm, and its tension is 729 N, what is the fundamental frequency (in Hz)?

Q3.

A vertical tube one meter long is open at the top. It is filled with 66 cm of water. If the velocity of sound is 344 m/s, what will the fundamental resonant frequency be (in Hz)?

Q4.

Two tuning forks with frequencies 255 Hz and 262 Hz produce "beats". What is the beat frequency (in Hz)?

Q5.

Two instruments produce a beat frequency of 6 Hz. If one has a frequency of 623 Hz, and the other has a higher frequency, what could be the frequency of the other instrument?
