WebMicrowaves cause water and fat molecules to vibrate, which makes the substances hot. So we can use microwaves to cook many types of food.. Mobile phones use microwaves, as they can be generated by a small … WebIn a microwave oven, the water and fat in food absorb the microwaves, which heats up the outside of the food. Conduction transfers energy to the middle. Infrared radiation cooks food in a grill or oven. Infrared from a radiator can heat you up by transferring energy to a thermal store. Lasers in CDs, DVDs, and Blu-ray Discs use visible light.
WebElectromagnetic (EM) waves carry energy and so can transfer energy from one point to another point. EM radiation is an energy transfer pathway. EM waves with a shorter wavelength carry a higher energy. This includes UV, X-rays and gamma rays. The higher the energy of the EM wave, the more dangerous it is.
