Do you know the formula for energy, given frequency and wavelength?

4. theEric

If I remember correctly, $$E=hf$$. Is that right?

5. anonymous

WHAT IS IT?

6. theEric

Energy is proportional to frequency, if that is correct. Then low energy means low frequency. Also, we have speed being the frequency times the wavelength.$v=f\lambda$So $f=\frac v \lambda$So wavelength is inversely proportional to frequency. What does that tell you?

Haha, I won't answer THAT. But I will answer any questions pertaining to my explanation.
