Question

Calculate propagation constant and angular frequency of light waves of wavelength 700nm travelling in free space

Answer 1

Answer:

In the case of electromagnetic radiation—such as light—in free space, the phase speed is the speed of light, about 3×108 m/s. Thus the wavelength of a 100 MHz electromagnetic (radio) wave is about: 3×108 m/s divided by 108 Hz = 3 metres.
