Question

The magnetic field associated with a light wave is given by

Answer 1

Answer:

As we know, light is a electromagnetic wave that has a wavelength that lies in the visible spectrum.

Hence, we denote a electromagnetic wave as the propagating transverse wave of oscillating electric and magnetic fields, that is they travel perpendicular to each other. This shows an oscillating electric fields produce a magnetic field (B) ;

B= Bo [cos (kx-wt) ]  → light wave associated with a light wave.
