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
