Explanation:
light does not need a medium
it is refracted
Light is made up of little packets of energy called photons.
electromagnetic waves
Light is created by vibrations in electric and magnetic fields because the light is an electromagnetic wave, therefore the correct answer is option C
What is an electromagnetic wave?
The oscillation of an electric field and a magnetic field produces electromagnetic waves, which are waves. In other words, electromagnetic waves (EM waves) are made up of vibrating magnetic and electric fields that are orthogonal to one another.
It is undeniable that we experience solar radiation, which is an electromagnetic wave that originates from the sun and can travel through space to the planet.
Light is a form of electromagnetic which is made up of the electric and magnetic filed that are orthogonal to each other, light can travel without any medium.
Thus, Light is created by vibrations in electric and magnetic fields, because the light is an electromagnetic wave, therefore the correct answer is option C
