Describe how magnetic and electric fields interact, specifically with regards to light.

The electromagnetic field propagates at the speed of light (in fact, this field can be identified as light) and interacts with charges and currents.

Explanation:The electric field is produced by stationary charges, and the magnetic field by moving charges (currents); these two are often described as the sources of the field.

layers of the earth affect the waves and these effects are seen on instruiments such as seimometers

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
