Identifying radiation based on a wavelength

Postby camrynpatterson3C » Mon Oct 16, 2017 3:04 pm

Hi guys!
Does anyone know if we will have to be able to identify what kind of radiation something is based on its wavelength, on the test?
For example, #44 on the Atomic Spectra Post-Module Assessment.

We must know the visible light spectrum (700-400 nm). Anything greater than 700 is infrared, values slightly below 400 fall into the UV spectrum. I don't believe we need to know the spectrum to the extent of differentiating microwaves and x-rays...

I do not believe we need to know the specific ranges of wavelengths on the spectrum (x-rays, microwaves, radio waves, etc) though it would not hurt and I would definitely learn their general positions (longer/shorter wavelength). I know one question in the book asked which color in the visible spectrum a wavelength correlated to but I am doubtful this will be on a test (but it is possible). As stated above, knowing the range of visible light and where infrared and ultraviolet light is on the spectrum is probably enough.

On the test I took yesterday, the values were given to me. However, I agree with what others have been saying and recommend knowing their differences because wavelength relates to the key concepts of this chapter.
