One end of a long rope is tied to a fixed vertical pole. The rope is stretched horizontally with a tension 8 N. Let us consider the length of the rope to be along X-axis. A sample harmonic oscillator at x = 0 generates a transverse wave of frequency 100 Hz and amplitude 2 cm along the rope. Mass of a unit length of the rope is 20 gm/m. Ignoring the effect of gravity, answer the following questionsTension in the given rope remaining the same, if a simple harmonic oscillator of frequency 200 Hzis used instead of the earlier oscillator of frequency 100 Hz, then

Answer»

speed of transverse WAVES in the rope will be doubled, wavelength will not change
speed of transverse waves in the rope will become HALF, wavelength will become one-fourth
speed of transverse waves in the rope will become FOUR times, wavelength will be doubled
speed of transverse waves in the rope will not change, wavelength will become half
