We know that the speed of a wave (v), frequency (f), and wavelength (λ) are related by the equation: v = fλ. We are given v = 3.0 × 108 m/s and λ = 5.0 × 10-7 m. We need to find f. Rearranging the equation to solve for f, we get: f = v / λ. Substituting the given values: f = (3.0 × 108 m/s) / (5.0 × 10-7 m) = 6.0 × 1014 Hz.
