Q10(a). A wire having a linear density 5g/m is stretched between two rigid supports with a tension of 450N. The wire resonates with a frequency of 450 Hz. [4M] (1) If next higher frequency at which the same resonates is 525 Hz, find the vibrating length of the wire. (2) Find the no. of nodes present in both cases. (3) Find the speed of the wave. (4) If the tension is increased by 21%, find the percentage increase in the frequency of the transverse wave along the string. b) Yellow light of wavelength 595nm is used to produce interference fringes with Young's double slit set-up. Find angular location of the third order interference maximum for a slit separation of 0.10mm. [4M)
