A student generates a table enumerating various electromagnetic waves along with their energy levels, measured in electron volts.

electromagnetic wave:
Microwave
Ultraviolet
X-Rays
?

Energy (eV) :
0.00001
10
30,000
5,000,000

with what electromagnetic wave does the student fill in the question mark in the table?
visible light waves
gamma rays
radio waves
infrared waves

Based on the given energy levels, the student can fill in the question mark in the table with "gamma rays". Gamma rays have higher energy levels compared to microwave, ultraviolet, and x-rays.
