Sciencedoze: Science, Education and Technology

Some scientific discoveries came after long research and experimenting but many of them came accidentally. Accidental scientific discoveries proved to be a game-changer in today's life. So here are 5 incredible inventions that were discovered by accident. 1. Microwave oven The microwave oven was invented by Percy Spencer entirely by accident. He was working on "magnetron" , one of the components of radar equipment. He was amazed to see that candy in his pocket had melted.  Out of curiosity, he tried placing other objects near magnetron like popcorn, eggs, etc (He was standing at a safe distance, so as not to start cooking himself). Popcorn started popping out and eggshells started exploding, and for the first time, he came to know that eggs will explode in their shells if cooked in a microwave. Spencer realized the potential of his invention and designed more efficient and reliable food-cooking microwave ovens. The early models were not received much popularity due to t

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
