Question

The mass of a string is 6 grams, and it is stretched so that its tension is 150 N. A transverse wave travelling on this string has a frequency of 160 Hz and a wavelength of 0.40 m. What is the length of this string? (ii) A chain saw has a measured sound level of 80 dB. What is the intensity of this sound in W/m2?
