### 7th Edition Book, Section 1.A #9

In the 7th Edition Book, Section 1.A #9 it asks for us to fill out a chart. I understand the first three columns, but don't understand the last column that says "event." How do we know the event based on the answers we found and are given? Is there a chart that tells you the event based on the number you get?

four events are mentioned in the question, you just need to infer the type of electromagnetic wave in each row using the wavelength you get, and then knowing the type of wave gives you the event

As stated above, there were four different events listed: reading, getting a dental x-ray, making popcorn in a microwave oven, and acquiring a suntan. Keep in mind that these all have different wavelengths.
