wavelength = 3.00*10^8 m/s
------------------- that is division.
5.3* 10^2 Hz
\(\frac{3*10^8m/s}{5.3*10^2 Hz}\\ =\frac{3*10^6m/s}{5.3 \;oscillations/sec}\\ \approx \frac{566038m}{oscillations}\\~\\ wavelength = 566038m\;\;\text{to the nearest metre}\)
i got 566.038
You answer is not right becasue 3/5.3 = 0.5660377...
10^8 / 10^2 = 10^6
0.5660377 * 10^6 = 566037.7
