Shopping on line can be easy, simple and save you lots of money. It can also take a lot of your time, frustrate you, and result in unwanted purchases. Now the same can be said for regular high street shopping, but with the vast opportunity presented by the Internet it will pay you to spend a few minutes reading this and understanding how to better optimize your Rayleigh Scattering shopping experience:

1. Compare - without doubt the biggest advantage that the Rayleigh Scattering offers shoppers today is the ability to compare thousands of Rayleigh Scattering at a time. This is a great thing, but not necessarily all the time! Too much can be daunting at times so take advantage of the great comparison sites and where possible let them do the hard work for you.

2. Research - if it has been said it will be on the internet. Ignorance is no longer a justifiable reason for buying the wrong thing. Take the time to research in detail everything that you could possible want to know about

3. Testimonials - don't know anybody that has bought a Rayleigh Scattering? Wrong! If the Rayleigh Scattering is good the internet will let you know. Use the Internet as a friend and get testimonials before you buy.

4. Questions - Got a question about Rayleigh Scattering then search the Forums, FAQ's, Blogs etc. Don't be afraid to ask .....

5. Reputation - Never heard of the company selling Rayleigh Scattering? Don't worry, no reason why you should know every company in the world, but you know someone that does! Use the internet to find out what people are saying about Rayleigh Scattering and build up a picture of their reputation for sales, returns, customer service, delivery etc.

6. Returns - still worried that even after all of the above your Rayleigh Scattering wont be what you want? Check out the returns policy. There is so much competition now that someone, somewhere is bound to offer the terms that you are comfortable with.

7. Feedback - happy with your Rayleigh Scattering then let people know, after all you are depending on others people input in your buying decision, so why not give a little back.

8. Security - check for the yellow padlock on the Rayleigh Scattering site before you buy, and the s after http:/ /i.e. https:// = a secure site

9. Contact - got a question about Rayleigh Scattering, or want to leave a comment then check out the sites contact page. Reputable companies have them and respond.

10. Payment - ready to pay for your Rayleigh Scattering, then use your credit card or PayPal! Be aware of companies that don't accept them, there may be genuine reasons but given the huge amount of choice you have when buying online there is no reason at all not to buy via credit card or PayPal.

Rayleigh scattering (named after Lord Rayleigh) is the scattering of light or other electromagnetism radiation by particles much smaller than the wavelength of the light. It can occur when light travels in transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering of sunlight in clear atmosphere is the main reason diffuse sky radiation. Rayleigh and cloud-mediated scattering contribute to diffuse light (direct light being sunrays).

For scattering by particles similar to or larger than a wavelength, see Mie theory or discrete dipole approximation (they apply to the Rayleigh regime as well).

Small size parameter approximation

The size of a scattering particle is defined by the ratio (x) of its characteristic dimension (r) and wavelength (λ): x = \frac{2 \pi r} {\lambda} . Rayleigh scattering can be defined as scattering in small size parameter regime x
