Microwave ovens are so quick and efficient because they channel heat energy directly to the molecules (tiny particles) inside food. Microwaves heat food like the sun heats your face—by radiation. A microwave is much like the electromagnetic waves that zap through the air from TV and radio transmitters. It’s an invisible up-and-down pattern of electricity and magnetism that races through the air at the speed of light (300,000 … Read moreDMPQ- Explain the functioning of microwave.
India’s latest communication satellite GSAT-30 was successfully launched from the Spaceport in French Guiana. With a lift-off mass of 3357 kg, GSAT-30 will provide continuity to operational services on some of the in-orbit satellites.
