Huygen's principle allows us to understand and determine.
- A The wavelength of the wave
- B The velocity of the wave
- C The amplitude of the wave
- D The propagation of wavefronts
Answer & Solution
Correct Answer
(D) The propagation of wavefronts
Step-by-step Solution
Detailed explanation
Huygens's Principle states that every point on a primary wavefront acts as a source of secondary spherical wavelets. By finding the "envelope" that is tangent to all these wavelets at a later time, we can determine the new position and shape of the wavefront as it propagates…
