Q.19. The figure shows a wave of frequency 1200 Hz spread over a length of 10 m. Whatis wavelength of the wave? What is speed of the wave?

[2 m, 600 Hz]

Dear Student ,
Here in this case total 5 full waves are present so here the wavelength of the wave is ,
λ=105=2 mSo the speed of the wave is ,V=ν×λ=2×1200=2400 m/s
