What color of light is not absorbed by a blue object? So what happen to the absorbed colours? When white light falls on a blue surface, it reflects only blue and absorbs all other wavelengths. In fact blue is also first absorbed and then re emitted. Why might I see a surface as blue and […]
What are the two types of EMC standards?
What are the two types of EMC standards? EMC emission and immunity standards are developed to specify terms, measurement methods, limits for conducted and radiated electromagnetic emissions and level of minimum immunity (susceptibility). What is EMC category? EMC stands for electromagnetic compatibility – the ability of electric and electronic devices to work properly in the […]
Can matter be created or destroyed?
Can matter be created or destroyed? Matter is anything that has mass and takes up space. Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law […]

Is speed directly proportional to distance?
Is speed directly proportional to distance? – Speed (s) is defined as the rate at which distance is covered during the motion and it is measured in distance per unit time. – When time is constant, then speed is directly proportional to distance. – When the distance is constant, then speed is inversely proportional to […]
