Explanation:
Huygen's wave theory of light was proposed by Dutch physicist Christiaan Huygens in the 17th century. According to this theory, light travels in the form of waves and these waves spread out in all directions from the source of light. However, Huygen's wave theory of light has certain limitations and cannot explain some phenomena related to light.
The limitations of Huygen's wave theory of light are as follows:
1. Photoelectric Effect: Huygen's wave theory of light cannot explain the photoelectric effect, which is the emission of electrons from a metal surface when it is exposed to light. The photoelectric effect can only be explained by the quantum theory of light, which suggests that light is made up of discrete particles called photons.
2. Interference: Huygen's wave theory of light can explain the phenomenon of diffraction, which is the bending of light around obstacles or through narrow openings. However, it cannot explain interference, which is the phenomenon of light waves interacting with each other to produce regions of constructive and destructive interference.
3. Polarization: Huygen's wave theory of light cannot explain the phenomenon of polarization, which is the alignment of light waves in a particular direction. Polarization can only be explained by the wave theory of light, which suggests that light waves have a transverse nature.
In conclusion, Huygen's wave theory of light is a useful concept that explains many phenomena related to light. However, it has certain limitations and cannot explain some of the more complex phenomena such as the photoelectric effect, interference, and polarization. These phenomena require the use of more advanced theories such as quantum mechanics and electromagnetism.
