Light moving through water or glass is slower. As
wavelength * fraquency = speed,
what changes: wavelength, frequency or both ?
Another question: what we observe as the colour of light,
does this correspond to energy, frequency or wavelength ?
And a third: are the physicists able to measure
amplitude, frequency and wavelength of light ?
