In interference and diffraction, the light energy is redistributed. If it reduces in one region, producing a dark fringe, it increases in another region, producing a bright fringe. A. As there is no gain or loss of energy, these phenomena are consistent with the principle of conservation of energy. B. Diffraction and interference are characteristics exhibited only by light waves. Choose the correct answer from the options given below:

Solution & Explanation

Iavg = constant
Core Logic

Statement A is true because energy is redistributed without creation or destruction. Statement B is false because interference and diffraction are general wave phenomena exhibited by sound waves and matter waves as well.

Pattern Recognition

Wave phenomena conservation of energy and universality to all wave types.

Q13 neet_2024_05_may_morning Young's Double Slit Experiment
In Young's double slit experiment, using monochromatic light of wavelength λ , the intensity of light at a point on the screen where the path difference is λ , is K units. The intensity of light at a point where the path difference is (λ)/(3) will be
  • A. (K)/(4)
  • B. K
  • C. (K)/(2)
  • D. 2K

Solution

Related Formula
I = I₀ ²((Δ φ)/(2)) = I₀ ²((π Δ x)/(λ))
Core Logic

When Δ x = λ: I = I₀ ²(π) = I₀ = K. When Δ x = (λ)/(3):

I₁ = I₀ ²((π)/(λ) · (λ)/(3)) = I₀ ²((π)/(3)) = (I₀)/(4) = (K)/(4)
Pattern Recognition
