8) A stationary wave is produced along a stretched string with a wavelength of 4 cm by vibrating both ends of the string simultaneously. The length of the string is 12 cm.(a) Draw the wave profile of the stationary wave produced.(b) What is the frequency of this wave if the velocity of the wave in the string
is 50 cm s-1?(c) Draw a graph with the y-axis as phase and the x-axis as the distance along
the string measured from one end to show the variation of phase along the string.
