What do we mean by the frequency of electromagnetic radiation Is the frequency the same as the speed of the electromagnetic radiation?

The frequency of electromagnetic radiation refers to the number of oscillations or cycles of the electromagnetic wave that occur in one second, measured in hertz (Hz). It is not the same as the speed of electromagnetic radiation; while frequency indicates how often the waves occur, the speed refers to how fast the waves travel through space. In a vacuum, all electromagnetic radiation travels at the speed of light, approximately 299,792 kilometers per second, regardless of its frequency. The relationship between frequency (f), wavelength (λ), and speed (c) is defined by the equation: ( c = f \times λ ).
