• There is something that you need to pay attention- the significant configeration. In this case, the light speed has 3 sc. the frequency have 3. So the wavelength should only have 3.

# the quiz might be really easy. But you need to understand what we are doing here. We consider the frenquency directly connect to the energy. This calculation tells you how to get the energy information for lights.
