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

With what electromagnetic wave does the student fill in the question mark in the table?

a. gamma rays
b. visible light waves
c. radio waves
d. infrared waves

1 answer

To determine with which electromagnetic wave the student should fill in the question mark in the table, we can analyze the energy levels of the different types of waves.

Gamma rays have the highest energy levels among the options provided. They can range from about 100,000 electron volts (eV) to several million eV.

Visible light waves have energy levels ranging from about 1.65 eV (red light) to 3.1 eV (violet light).

Radio waves have very low energy levels, typically in the range of micro electron volts (μeV) to milli electron volts (meV).

Infrared waves have energy levels ranging from about 0.04 eV to about 1.6 eV.

Comparing these energy levels, we see that the energy level of the missing electromagnetic wave is higher than the energy levels of visible light, radio waves, and infrared waves, but lower than the energy levels of gamma rays. Therefore, the missing electromagnetic wave falls within the energy range of X-rays.

The answer would be e. X-rays.
