Answer
Answer e, or red light, is third in the list.
Work Step by Step
To figure out the answer to this, we must first analyze the question, which is asking us to list the types of electromagnetic radiation in order of increasing wavelength. Therefore, we can refer to Figure 6.4, on page 215.
Looking at Figure 6.4 tells us that red light has a higher wavelength than yellow light within the visible spectrum, and has a higher wavelength than gamma rays. However, radio waves (like AM and FM radio signals) are the longest waves, and are have longer wavelengths than the visible spectrum. Therefore, option e is the third in the list.
