Q. What is the electromagnetic spectrum and how is it described?

AI Thread Summary
Electromagnetic waves are oscillations of electric and magnetic fields that travel through space, characterized by properties such as wavelength and frequency. The electromagnetic spectrum encompasses a range of electromagnetic waves, from gamma rays with high frequency and short wavelength to radio waves with low frequency and long wavelength. Each type of wave has distinct properties and applications, including medical imaging for gamma rays and communication technologies for radio waves. The discussion highlights the importance of basic research skills, as participants express frustration over the lack of effort in finding information. Understanding the electromagnetic spectrum is essential for various scientific and practical applications.

Hi... I m unable to find the answer for these questions...

Q. What are electromagnetic waves? State its properties.
Q. What is electromagnetic spectrum? Describe complete em spectrum from gamma rays to radiowaves in terms of frequency,wavelength,production, atleast 2 properties each,applications,etc.

Welcome to Physics Forums. Are these homework problems?
 
Unable to find? I find that hard to believe. What did you try, search-wise? I pasted "electromagnetic waves" into Wikipedia and into Google search and got useful results. No problem.
 
Haha this is obviously homework
they can't even be bothered to google it let alone open their textbook
 
I would have thought that googling 2 words would be easier than typing the post.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
