Answer

$\frac{10}{3}$ $m$

Work Step by Step

Given , speed of the waves = $3\times10^{8}$ $\frac{m}{s}$ and frequency = $9\times10^{7}$ $\frac{waves}{s}$ Now, wavelength = $\frac{speed}{frequency}$ $=$ $\frac{3\times10^{8} m/s}{9\times10^{7}waves/s}=$ $\frac{10^{8-7}}{3}$ $m$ Hence, wavelength $=$ $\frac{10}{3}$ $m$
