Chapter 4: Problem 156

Which electromagnetic radiation is most dangerous to humans? (a) X-rays (b) Ultraviolet light (c) Gamma rays (d) Infrared light (e) Radio waves

Short Answer

Expert verified
The most dangerous electromagnetic radiation to humans is (c) Gamma rays, as they have the highest energy levels among the options listed.

Step by step solution

01

Identifying the order of energy levels in electromagnetic radiation

Electromagnetic radiation can be categorized in the following order based on their increasing energy levels: radio waves, infrared light, visible light, ultraviolet light, X-rays, and gamma rays.
02

Comparing the listed options in the exercise

In the given exercise, all options except visible light are listed. These include: X-rays, ultraviolet light, gamma rays, infrared light, and radio waves. According to the order identified in Step 1, we can see that the energy levels increase as follows: radio waves < infrared light < ultraviolet light < X-rays < gamma rays.
03

Identify the most dangerous radiation for humans

Based on the energy level comparison in Step 2, gamma rays have the highest energy levels among the options listed in the exercise. Therefore, the type of electromagnetic radiation that is most dangerous to humans is: (c) Gamma rays
