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 'Maxwell stress tensor'

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
