in what ways is specroscope, or spectrum used in today's technology?

Question

What are two ways that the skill of spectroscopes used in today's techonology?

Answer 1

The water than comes out of the tap in your kitchen has likely been analyzed by flame, furnace, or "Inductively-Coupled Plasma" spectroscopy to ensure it contains less than certain levels of potentially harmful metals and other elements.

Many blood & urine tests are performed in hospital labs using spectroscopy, too.

Answer 2

No, I do not use social networking. I'm not a social person by nature, but I don't think I would anyway... I try not to spend a lot of time in front of a screen. I check my email regularily, I often go on Youtube (mostly for music - I'm a guitarist) and occassionally I visit Yahoo answers... I do little research online and I never use MSN messager like so many of my peers. Most of the people I know who are around my age (15-16) spend about 4-6 hours every night on facebook or msn. It's mostly pointless chatter that couls just as well be done at school the next day, let alone over the phone or actually face-to-face with the person outside of school. There's such a thing as being too connected socially. I don't see why a person needs to be carrying on a conversation with their friends all day. To me it seems like an invasion of privacy and a huge waste of time. Having a social life is definitely a good thing - but it shouldn't become your only life.

Answer 3

Spectroscopes or Spectrum analyzers are used in order to provide us an image of a complex signal such as light or sound. One way that it is used for example, the use of spectrum analysis on a sound reveals the frequencies that consists the original sound(noise), its spectrum. Spectrum analysis is also used for light for example a gas can be identified through the colors(frequencies) that absorbs.

Answer 4

Since the spectrum of elements and their compounds is very specific, like a finger print, spectrum analysis is sometimes used to identify WHAT elements/compounds are present in a sample and also HOW MUCH of an element/compound is present in a sample.

examples:

Chemists involved in testing water use spectrum analysis to determine how much of a contaminant is present in the water.

Forensic scientists use spectrum analysis to determine if samples are similar.

Answer 5

Spectrophotometry is used to analyze whatever you like. Trace metals, residual pesticide, toxic substance in the body, etc. You can do this because metals, pesticides, etc. can absorb light (not all the time!), and you can use this data to measure their amount. Of course, you need a standard to do this. Mostly, quantitative chemistry stuff.
