Doubt in electromagnetic spectrum

Click For Summary
SUMMARY

The electromagnetic spectrum categorizes radiation based on wavelength, with gamma rays representing the shortest wavelengths below 10 picometers and radio waves encompassing wavelengths above 1 millimeter. This classification is not based on physical limitations but rather on human utility and convenience. High energy radiation is often referred to as high energy photons, indicating that the boundaries of these categories are somewhat arbitrary. The Wikipedia entry on the electromagnetic spectrum provides comprehensive information on these classifications.

PREREQUISITES
  • Understanding of electromagnetic radiation principles
  • Familiarity with wavelength measurement units (picometers, millimeters)
  • Knowledge of high energy photon concepts
  • Basic comprehension of the electromagnetic spectrum categories
NEXT STEPS
  • Research the properties of gamma rays and their applications in medical imaging
  • Explore the characteristics and uses of radio waves in communication technologies
  • Study the concept of high energy photons and their role in physics
  • Review the electromagnetic spectrum classification criteria and its implications
USEFUL FOR

Students of physics, researchers in electromagnetic theory, and professionals in telecommunications and medical imaging will benefit from this discussion.

In electromagnetic spectrum, why there is no radiation less than wavelength of Gamma rays and waves higher than the wavelength of Radio waves?
 
Physics news on Phys.org
The Wikipedia entry on the electromagnetic spectrum contains a lot of relevant information. There is no shorter wavelength than a gamma ray if you call all that is below 10 pm, but as Wikipedia points out, very high energy radiation is sometimes simply called high energy photons. Same for radio waves: all that is above 1 mm in wavelength is considered a radio wave.
 
yeah, It's really just an arbitrary assignment. We 'categorize' wavelengths according to how they are useful to us.
