Chapter 1: Question 1.9

A college student recently had a busy day. Each of
the student’s activities on that day (reading, getting a
dental x-ray, making popcorn in a microwave oven, and
acquiring a suntan) involved radiation from a different
part of the electromagnetic spectrum. Complete the
following table and match each type of radiation to the
appropriate event.

Based off what the information and what I found, which of these factor (Wave length, Frequency, or Energy of Photon) am I suppose to look at when trying to match the events to the data?

You can use the frequencies that you found, and were given to you, to match the events. A lower frequency would mean that it will have a weaker radiation, and higher frequencies would mean it is a stronger type of radiation.

Yup ^^ and because of that, you can also technically look at wavelengths with longer wavelengths having lower radiation and shorter wavelengths with higher radiation

It helps to think about what kind of wavelength each activity has.
