Given below are two statements: Statement I : In the interference pattern formed by two coherent sources each of intensity I₀ , the average intensity over the entire screen is 2I₀ , which confirms that the total energy remains conserved. Statement II : The phenomenon of interference is an exclusive property of transverse waves and cannot be demonstrated using longitudinal waves. Choose the correct answer from the opt

Options

  1. ABoth Statement I and Statement II are correct
  2. BBoth Statement I and Statement II are incorrect
  3. CStatement I is correct but Statement II is incorrect
  4. DStatement I is incorrect but Statement II is correct

Correct answer

C. Statement I is correct but Statement II is incorrect

Step-by-step solution

The intensity of the interference pattern produced by two coherent sources of intensity I₀ is given by I = I₀ + I₀ + 2 I₀ I₀ = 2I₀(1 + ) . The average intensity over the entire screen is I = 2I₀ + 2I₀ . Since the average value of over a complete cycle is zero, I = 2I₀ . The sum of the individual intensities is also I₀ + I₀ = 2I₀ . This shows that energy is merely redistributed and the total energy remains conserved. Thus, Statement I is correct. Interference is a characteristic property of all types of waves, inclu
