In outer space there is no atmosphere so turbines and propellers can not work there. This explains why a rocket works in space but a turbine engine or a […]
Why is it called electromagnetic?
Why is it called electromagnetic? The waves of energy are called electromagnetic (EM) because they have oscillating electric and magnetic fields. If it has low frequency, it has less energy and could be a TV or radio wave. All EM energy waves travel at the speed of light. No matter what their frequency or wavelength, […]
