Which is better natural or forced convection?
Which is better natural or forced convection? When considering the mechanism of forced convection, it is has a complicated mechanism than the natural way. That is because, in this method, we have to regulate two factors; fluid motion and heat conduction. Ex: higher the rate of motion of the fluid, higher the heat transfers. What […]

Can we see polarized light?
Can we see polarized light? Though most of us are unaware of our capacity to do so, humans can also perceive the polarization of light. We detect the orientation of polarized light using ‘Haidinger’s brushes’, an entoptic visual phenomenon described by Wilhelm Karl von Haidinger in 1844 [2]. How can you tell if light is […]
What are the two essential conditions for work done by a force acting on an object?
What are the two essential conditions for work done by a force acting on an object? For work to be done, it is essential that some force is applied to the object and the object displaces from its initial position. If these two conditions are satisfied, then the work is done. So, work done= force […]
