Select the WRONG statement.

Options

  1. AAccording to Huygens" principle, every point on a given wavefront is regarded as a secondary source.
  2. BThe new disturbance from secondary source travels in all directions with the velocity of light and is called s
  3. CThe surface of tangency to secondary wavelets in forward direction only gives new wavefront.
  4. DHuygens could explain rectilinear propagation of light.

Correct answer

D. Huygens could explain rectilinear propagation of light.

Step-by-step solution

Checking the given options: According to Huygens' principle, every point on a given wavefront is regarded as a secondary source. This statement is correct. The new disturbance from secondary source travels in all directions with the velocity of light and is called secondary wavelets. This statement is correct. The surface of tangency to secondary wavelets in forward direction only gives new wavefront. This statement is correct. Huygens could explain rectilinear propagation of light. This is the wrong statement.
