- Hey professor Jeff! I heard from your students that they haven't fully understood your lectures regarding the Electromagnetic Spectrum.I was hoping that you could tell me about it so I can make them understand better. The textbooks are no good either so I'm hoping to have some of your time knowing that you are a busy person.
- Oh. Why didn't you say so? I could have sworn that no one wanted to ask questions after the lecture. I'm guessing they were too shy to ask which I can understand but it would have been better to be honest. Anyways, it won't take too long so here's the gist of it:
- The Electromagnetic Spectrum is simply a list of all the EM radiation and their wavelengths and frequency. It is arranged in descending order of wavelength. With Radio being the longest and Gamma Rays being the shortestThe spectrum goes like this: Radio, Microwave, Infrared, Visible Light, Ultraviolet Rays, X-rays, and Gamma Rays.
- The frequency (and energy) of the radiation is inversely proportional to the wavelength. Meaning the shorter the wavelength, the higher the frequency.Because Ultraviolet Rays have frequencies and can be dangerous when exposed for an extended time leading to sunburns or worse, cancer.
- In my eyes, the Electromagnetic Spectrum wouldn't have become what it is today if it weren't for the efforts of multiple brilliant people. They all contributed to it and that answer is sufficient.
- I see. Thanks Jeff. Oh and, I have a question: Do you know who made the Electromagnetic Spectrum?
- 1st
- Alright, I understand now. Thank you for sparing me your time Jeff. I'll treat you for lunch later!
- No problem! I wish to make it easier for my student to learn so I'll definitely improve on making my teachings clearer.
