What does Huygen’s Principle state about wavefronts?
What does Huygen’s Principle state about wavefronts?
- Wavefronts are stationary and do not propagate
- Every point on a wavefront may be considered a source of secondary spherical wavelets which spread out in the forward direction at the speed of light (correct)
- Wavefronts move at a speed proportional to their wavelength
- Wavefronts are composed of individual particles

- They refract and disperse into different colors
- They transform into electromagnetic waves
- They create interference patterns
