Physics Principles Around Us
From this video, I have started a series of Physics Principles around us (Me), where I will share which physics principle is used to make a particular device. Like here the first microphone is selected.
This is an introductory video and soon you will get in parts with complete details. The second video is based on a type of microphones on the basis of physics principles. The detail of physics principles is explained first in pure form and how one can use that for creating a new product.
Also, an effort to motivate students so they can do more science experiments and understand physics lab role in their life and carrier. If my efforts are in the right direction you will definitely get ideas, to create a new product.
