EXERCISE 6.1 Concepts of Wavelength and Frequency
Two electromagnetic waves are represented in the margin. (a) Which wave has the higher
frequency? (b) If one wave represents visible light and the other represents infrared radiation,
which wave is which?

(a) Wave 1 has a longer wavelength (greater distance between peaks). The longer the wave-
length, the lower the frequency (v
Wave 2 has the higher frequency.

(b) The electromagnetic spectrum (Figure 6.4) indicates that infrared radiation has a longer
wavelength than visible light. Thus, Wave 1 would be the infrared radiation.
