Homework Answers
3-Waves of electromagnetic fields are known as electromagnetic waves. These waves are made of electric and magnetic fields. They propagate along the normal direction of both electric and magnetic fields. their waves propagate with speed of light c= 3* 10^8 m/sec in the vacuum.
These waves are different from other waves cause they have both electric and magnetic fields and they can travel through without any medium or vacuum. e.g. sunlight from the sun to earth.
4- Increasing frequency electromagnetic waves
radio wave - radio communication
