Atomic Structure

The test was handed back on Friday. We also started the Atomic Structure Unit; worksheets were handed-out.



Electromagnetic Energy - Light Energy

Light Energy is a form of energy that is transferred by radiation and is thought to move in the forms of waves.

Frequency - cycles per unit in time. (eg. in lightwave - the # of cycles pass a point in one second)



Wavelength is the distance between the crest or troughs. The wavelength of visible light is mostly measured in nanometres.

___________________________________________

Line Spectrum is a spectrum in which energy is concentrated at particular wavelengths; produced by excited atoms and ions as they fall back to a lower energy level.

Continuous Spectrum is when all the wavelengths of lights are represented. Line Spectrum on the other hand, is a distinct of coloured lines rather than a rainbow. In an element, the line spectrum is unique in each ones; no two elements have the same atomic emission spectrum. It's like a fingerprint.

I hope these helped you with the Assignment. =)

Oh yeah. Next Scribe will be Ruschev.
