Initial data: λ (wavelength of blue light in an airless environment) = 500 nm (500 * 10 ^ -9 m).
Constants: υ (speed of propagation of electromagnetic waves) = 3 * 108 m / s = C (speed of light).
The frequency of blue light waves is determined by the formula: ν = υ / λ.
Let’s calculate: ν = 3 * 10 ^ 8 / (500 * 10 ^ -9) = 600 * 10 ^ 12 Hz = 600 THz.
Answer: The frequency of blue light waves is 600 THz.
