electromagnetic waves

electromagnetic waves

When electromagnetic waves travel through a medium, the speed of the waves in the medium is v = c/n (λ free ), where n (λ free) is the index of refraction of the medium. The index of refraction n is a properties of the medium, and it depends on the wavelength λ free of the EM wave

the production of em waves - university of tennessee

When electromagnetic waves travel through a medium, the speed of the waves in the medium is v = c/n, where n is the index of refraction of the medium. When an EM wave travels from one medium with index of refraction n 1 into another medium with a different index of refraction n 2, then its frequency remains the same, but its speed changes, and therefore it wavelength changes. For air n is nearly equal to 1, for …
