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]**

Here in this case total 5 full waves are present so here the wavelength of the wave is ,

$\lambda =\frac{10}{5}=2m\phantom{\rule{0ex}{0ex}}Sothespeedofthewaveis,\phantom{\rule{0ex}{0ex}}V=\nu \times \lambda =2\times 1200=2400m/s$

Regards
