What is an electromagnetic spectrum? Arrange the given electromagnetic radiations in the decreasing order of their frequencies. Infrared rays, X-rays, UV rays, gamma rays.

The electromagnetic spectrum encompasses all types of electromagnetic radiation, which vary in wavelength and frequency. This spectrum includes everything from radio waves to gamma rays, each serving different purposes in technology and science.

Types of Electromagnetic Radiation

Here are the types of radiation mentioned, arranged in decreasing order of their frequencies:

• Gamma rays
• X-rays
• Ultraviolet (UV) rays
• Infrared rays

In this arrangement, gamma rays have the highest frequency, while infrared rays have the lowest among the listed types. Understanding this order helps in grasping how different types of radiation interact with matter and their applications in fields like medicine and communication.
