Two plane polarized light waves combine at a certain point whose electric field components are aligned & E ₁= E ₀ t & E ₂= E ₀ ( t + 3 ) aligned Find the amplitude of the resultant wave.

Options

  1. A0.9 E
  2. BE ₀
  3. C1.7 E ₀
  4. D3.4 E ₀

Correct answer

C. 1.7 E ₀

Step-by-step solution

E = ( E ₀ )^2+ ( E ₀ )^2+2 ( E ₀ ) ( E ₀ ) 3 E = 2 E ₀^2+ E ₀^2 = 3 E ₀=1.73 E ₀
