A. The speed of light decreases in glass
B. The energy of light increases in glass
C. The frequency of light decreases in glass
D. The wavelength of light inreases in glass

Question

anonymous · Answer

Moving to a more dense medium decreases the speed of the light wave. From the wave equation C=f(lambda) , if the frequency f remains the same and the speed of the wave C goes down, what happens to lambda (the wavelength)? It must go __ ?
