up A standing wave is set up in a string of variable length and tension by a vibrator of variable frequency Both ends of the string are fixed When the vibrator has a frequency f in a string of length L and under tension T n antinodes are set in the string a If the length of the string is doubled by what factor should the frequency be changed so that the same number of antinodes is produced b If the frequency and length are held constant what tension will produce n 1 antinodes c If the frequency is tripled and the length of the string is halved by what factor should the tension be changed so that twice as many antinodes are produced
