Unformatted text preview: T . Suppose the density of the string is ρ . Find out at what frequency this string can vibrate. 5. There are two sound waves coming from two diﬀerent sources. The ﬁrst one has a frequency of 400 Hz and the second one has a frequency of 1200 Hz . The wave amplitude of the ﬁrst one is twice of that of the second one. Find out the ratio of the intensity of the ﬁrst wave to the second one 1...
