Monochromatic electromagnetic radiation illuminates an area of a surface. the electric andmagnetic fields of the waves are then doubled in magnitude. how is the total energy incident on the surface per unit time affected by this increase in electric and magnetic fields?

the answer for apex is the lowest

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
