Answer:
The correct choice is
C. How much energy the wave has
Explanation:
The energy carried by a wave is given as
E = hc/λ
where
E = Energy carried by the light wave.
h = plank's constant
c = speed of the light wave
λ = wavelength of the light wave.
Hence the energy carried by the light is inversely related to the wavelength. Larger the wavelength, smaller will be the energy carried by the wave. Â Smaller the wavelength, larger will be the energy carried by the wave.
