The diagram shows three types of electromagnetic radiation and their range of frequencies. Portion of
Electromagnetic Spectrum
infrared
ultraviolet
1012 10" 104 105 106 107
Frequency, f(Hz)
Which explanation correctly uses the data in the diagram to show how Infrared radiation and
ultraviolet radiation are related in terms of energy?
A. Ultraviolet radiation has less energy than infrared radiation because energy is inversely proportional to
frequency and the frequency of ultraviolet radiation is higher.
B. Ultraviolet radiation has more energy than infrared radiation because energy is inversely proportional to
frequency and the frequency of ultraviolet radiation is lower
C. Ultraviolet radiation has less energy than infrared radiation because energy is proportional to frequency
and the frequency of ultraviolet radiation is lower
D. Ultraviolet radiation has more energy than Girared radiation because energy is proportional to
frequency and the frequency of ultraviolet radiation is higher.
