Correlating Energy and Frequency of Radiation
Which is higher in energy, FM radio waves with a frequency of 1.015 × 10^{8} Hz (101.5 MHz) or visible green light with a frequency of 5 ×10^{14} Hz?
Strategy
Remember the equations \epsilon =h\nu and \epsilon =hc/\lambda , which say that energy increases as frequency increases and as wavelength decreases.
The blue check mark means that this solution has been answered and checked by an expert. This guarantees that the final answer is accurate.
