find the wavelength of a wave that has a frequency of 6.29 Hz Remember c=2.998 x 10^8 m/s?
4.34 x 10^8m
3.12 x 10^7m
4.77 x 10^7m
5.19 x 10^6m

So the speed of light is 2.998 x 10^8 m/s. That means that it travels 2.998 x 10^8 meters in one second. And then 6.29 Hz means that there are 6.29 waves in one second, so there are 6.29 waves in 2.998 x 10^8 meters. Just divide that distance by 6.29.
Remember to round off the the correct number of significant digits.

For any wave traveling through a linear media at constant velocity, the equation is:
λ = v/f
Where λ = wavelength, v = velocity and f = frequency.
λ = (2.998x10^8 m/s) / (6.29 Hz)
λ = (2.998/6.29)x10^8 m
λ = 0.477 x10^8 m
λ = 4.77x10^7 m

λ = c/f
