Consider the following statements about stationary waves A. The distance between two adjacent nodes or antinodes is equal to 2 ( = wavelength of the wave ) B. A pressure node is always formed at the open end of the open organ pipe. choose the correct option from the following

Options

  1. AOnly the statement A is true
  2. BOnly the statement B is true
  3. CBoth statements A and B are true
  4. DBoth statements A and B are wrong

Correct answer

C. Both statements A and B are true

Step-by-step solution

A: Fresnel’s diffraction → occurs when source/screen are at finite distance ✅ (True). B: Diffraction was used to estimate helical structure of nucleic acids (DNA, X-ray diffraction by Rosalind Franklin) ✅ (True). So, both A and B are true. ✅ Correct Answer: (1) A and B are true
