In case of linearly polarised light, the magnitude of the electric field vector

Options

  1. Adoes not change with time
  2. Bvaries periodically with time
  3. Cincreases and decreases linearly with time
  4. Dis parallel to the direction of propagation.

Correct answer

B. varies periodically with time

Step-by-step solution

The magnitude of electric field vector varies periodically with time because it is the form of electromagnetic wave.
