IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / â¦ 2). 6 people found this useful. Al Cohen.
That change in the refractive index dictates the change in the speed of the wave traveling through that medium, and thus the waves wavelength. Click to expand... I understand that the mentioned phenomena does occur, but my question is why, in an intuitive sense, frequency remains constant while wavelength does not.
