memorization?
Do we have to memorize the ranges of the EM spectrum? Like which wavelengths would be UV and which would be visible light?

Re: memorization?
It would probably be good to have a general idea of where different wavelengths fall on the spectrum. Visible light goes from approximately 700-400 nm, UV has a smaller wavelength that visible, and Infared has a larger wavelength than visible light.

Re: memorization?
I think it's good for us to know or at least have a general understanding of where the wavelengths are on the spectrum.

Re: memorization?
You should have a general understanding, not complete memorization but the basics of UV!

Hi,
I don't think we need to memorize the entire EMR spectrum, but it would be a good idea to know general ranges of certain light (e.g., visible light is 400-700nm, etc.).

Re: memorization?
Hello! In my discussion section my TA said that it would be a good idea to memorize the EM spectrum. This would generally include the actual wavelengths as you travel down the spectrum as well as which types of lights/rays appear where on the spectrum. My TA said it would be possible to have a question regarding the EM spectrum on the midterm. Hope this helps and good luck memorizing!

Re: memorization?
I would try to memorize probably the order of the EM spectrum. For instance, UV light comes before visible light which comes before infrared. I would also maybe try to understand the ballpark of the wavelengths of each.

Re: memorization?
Hi! I think it would be useful to know the spectrum.. at least the major ones like UV, visible, and infrared so that way if we are asked what range a certain wavelength falls under, we know the relative ranges :)

Re: memorization?
Hi. My TA mentioned that it is possible that we will see questions related to specific values of the electromagnetic spectrum on the midterm, so I do recommend looking over it and understanding ranges of values that associate with parts of it. Based on where you look, some illustrations/explanations have slightly varying values, so try to remember the approximate ranges. Hope this helps!

Re: memorization?
We probably do not have to memorize the specific wavelengths but should know the order of the spectrum and have at least a basic idea concerning the wavelengths

Re: memorization?
Like everyone else I think it is good idea to try to memorize the order of the spectrum. Adding on, knowing the Lymann and Balmer series is probably needed. During discussion we got a question assuming that we knew the wavelength was part of the Balmer series and my TA said mentioned we should expect the same situation during the midterm.

Re: memorization?
A good mnemonic that I've heard for memorizing the EM Spectrum is "Ryan May I Visit Ur X-Girlfriend?" for Radio, Micro, Infrared, Visible, Ultraviolet, X-rays, Gamma. However, I think conceptually the only important part to know of the EM spectrum is that this goes in INCREASING frequency/energy and DECREASING wavelength^^

Thank you for the mnemonic! It's so helpful

Re: memorization?
I think its a good idea to memorize the spectrum and to know in general what the wavelength ranges are for the visible light spectrum especially and the Lyman and Balmer series because of how much its mentioned and a general idea of the rest of the light ranges

Re: memorization?
If you memorize the order of the EM spectrum, that would help you out with the frequency and stuff. Also, using a mnemonic device can help as well. Here is one that you can use: "Real Men Ignore Looking Up X-Girlfriends". This way, you can memorize the order from lowest to highest frequency!
Re: memorization?
Hello! I think memorizing this would definitely help but a general idea of it is great! In high school we memorized the order: (R)aging (M)artians (I)nvaded (V)enus (U)sing (X)-ray (G)uns.
If shown the wavelength, remember that radio has low frequency waves and that gamma rays have the highest. As the frequency grows and increases, so does the wave's energy! As you go from radio to microwave and so on, the frequency becomes higher! I hope this helped!
