Data: λ (specified length of electromagnetic wave) = 3 * 10 ^ 3 nm (3 * 10 ^ 3 * 10 ^ -9 m, 3 * 10 ^ -6 m).
Constant data: υ (speed of propagation of an electromagnetic wave) ≈ С (speed of light) = 3 * 10 ^ 8 m / s.
The frequency of an electromagnetic wave with a given wavelength is determined by the formula: ν = υ / λ.
Calculation: ν = 3 * 10 ^ 8 / (3 * 10 ^ -6) = 10 ^ 14 Hz = 100 THz.
Answer: The sought frequency of the electromagnetic wave is 100 THz.
