When an EM wave goes into say a denser medium and its velocity is decreased how does its wavelength and frequency change? I read that the frequency remains constant but the wavelength changes. Is this true? If so does that mean the wave gets compressed when it enters a denser ...
Wavelength, when discussing light, also relates to color, but inversely; blue light has a shorter wavelength than red light. 6 Sound waves provide another comparison: high-frequency sounds are perceived as high-pitched, while the wavelength of sound waves affects the directionality and propagation ...
