Scattering of Light- Rayleigh Law of Scattering, Types and Examples

Image
Scattering of Light The phenomenon of absorbing light by particles and then re-emitting in all directions is known as the scattering of light. When a light is emitted from a source then it is absorbed by all the particles which is coming in its path and then scattered in all direction. This is nothing but scattering of light. We will discuss this phenomenon with respect to Rayleigh law of scattering. Types of Scattering of Light 1. Elastic or Rayleigh Scattering This is a type of scattering in which the size of the particles say 'a' is very less than the wavelength of light i.e a<< λ . So, there will be no change in the frequency and wavelength of scattered light. 2. Inelastic Scattering This is a type of scattering in which the size of the particles say 'a' is larger than the wavelength of the light i.e a>> λ . So, there will be a change in the frequency and wavelength of scattered light. Rayleigh's law of Scattering Rayleigh's law of Scatter

The 12 Principles of Green Chemistry

Image
Green chemistry is the branch of chemistry which aims at the designing of chemical products and processes to reduce or eliminate the generation of hazardous substances. Green chemistry promotes the green process, a healthy environment, and sustainable development. So, Green chemistry works on some set of principles called "12 Principles of green chemistry" . These principles were formulated by Paul T. Anastas. 12 principles of green chemistry are given below: 1. Prevention of waste or by-products This principle of green chemistry states that we should minimise or eliminate waste by-products rather than cleaning the waste after it has been created. For example, the production of plastic by-products should be minimised instead of cleaning it after its production. We should make a proper plan to minimise the waste at every step of the chemical process. 2. Maximum incorporation of the reactants (starting materials and reagents) into the final product This principle of green

5 Strange habits of Einstein that made him Genius

Image
Some say that great minds think alike, and that's up for debate, but they seem to have one thing in common- they have some strange habits. Albert Einstein , one of the smartest people ever, had a lot of quirks, like not wearing socks and napping with a metal spoon in his hands. Can you become a genius if you follow his example? Let's find out...   1. No Socks Yes, Albert Einstein hate socks for some reason. He never wore them at all. He wrote once in a letter to his wife, Elsa, that he had to wear high boots all the time just to hide his bare feet.   How could that benefit him?  Not much probably, but at least he had a reasonably strong immune system to stand against cold weather haha. Jokes apart, the only reason Albert Einstein didn't wear socks was because in his childhood, it took him just a day or two to make a hole in a new sock and that says something about Albert Einstein's mind. His thoughts were so important for him that any issue even
