How Many Types of Electromagnetic Waves Exist?

AI Thread Summary
The discussion centers on the types of electromagnetic waves, highlighting that there are several forms, including gamma rays, x-rays, UV light, visible light, microwaves, and radio waves. Participants note that the classification of these waves is largely semantic, as the electromagnetic spectrum is continuous. Visual aids, such as charts, are suggested to better understand the spectrum, including the lower frequency end. Ultimately, the conversation suggests that all electromagnetic waves can be considered as one continuous spectrum. The topic emphasizes the importance of understanding the nature of electromagnetic radiation as a unified concept.

How many kinds of electromagnetic waves are there in the Universe? And what are they?
 
Engineering news on Phys.org
i don't know how many kinds there are in the universe but I've studied gamma rays, x rays, UV light, visible light, microwaves, radiowaves. I may be missing one from the spectrum and it is not in sequential order.
 
The difference between the different 'kinds' of EM waves is purely semantic. The spectrum is continuous.
 
redgoat try googleing electromagnetic spectrum..

To give you an idea of the kinds of electromagnetic radiation, check out this chart
It has some good visual aids making it easier to grasp. The only part of the spectrum they didn't indicate is the low end (smaller frequencies, longer wavelengths)

Here's another chart that includes the low end

If you've followed the previous responses, you'll now have the answer: one!

Reminds me of the old riddle: how many grooves are on a vinyl record: two, one on each side.
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
