How does an electro-magnetic wave get its name
Electricity and magnetism are closely related. When you pass a current through a conductor, a magnetic field is produced.In continuously changing current, a disturbance is caused in the form of a wave, in both the magnetic field and electrostatic field. Hence electro-magnetic.Examples of this wave extends across a ...

What happens when red light hits a white surface
The surface will look Red, because white reflects all colours and absorb none. If you hit a red light on, say, green then that would look black because green will absorb all the red but if it was a green light then it would look green. Every colour, except white, ...

When voltage remains constant in a circuit an increase in resistance will cause
The physical equation governing voltage is V = IR, where V is voltage, I is current, and R is resistance. If V remains constant while R is increased, I or current must decrease. Increasing the resistance in a circuit is simply introducing a material that further resists or impedes the ...
