A student documents the energy and wavelength of various electromagnetic waves in the presented table. (The term "eV" denotes electron volts, a unit of energy.)

For the question mark, which electromagnetic wave should the student insert?

a. Infrared Wave
b. Microwave
c. Radio
d. Gamma Ray

To answer this question, we need to look at the energy and wavelength values in the table and match them with the corresponding electromagnetic wave.

Since the energy value for Gamma Ray is the highest (10^6 eV) and its wavelength is the lowest (10^-11 m), we can conclude that option d. Gamma Ray should be inserted in the table for the question mark. Gamma rays have the highest energy and shortest wavelength among the given options.
