Question

Choose the correct options after reading the passage.
According to principle of superposition, two waves y; = A sin(kx - 1) and y, = A sin(kx + ut)
superimpose on a string. Then the phenomenon will be coserved as a new kind of wave pattern
is vibrating with the 3* mode of vibration with frequency 256 Hz. The fundamental mode of
vibration is fo. The length of the string is 3 m. If the speed of the wave on the string is vm/s in the
3 mode of vibration and the linear mass density of the string is 0.02 /mthe tension in the string
SIN. There would be many modes of frequency of vibration, one of them is f Hz.
The possible value of would be
la) 425 HZ
(by 350 HE
IC) 480 Hz
