The equation relating a wave's propagation speed to its frequency and wavelength:

v = fλ

v is the progatation speed, f is the frequency, and λ is the wavelength.

Given values:

For an EM wave in a vacuum, v = c ≈ 3×10⁸m/s

λ = 0.07m

Plug in the given values and solve for f:

3×10⁸ = 0.07×f

f = 4.3×10⁹Hz
