Answer 2

Answer

→ The theory has some drawbacks also. He could not explain partial reflection and refraction at the structure of transparent media.

→ It was unable to explain phenomena such as diffraction, interference, and polarization. The theory predicts that the speed of light in the denser medium is more than in the rare medium.

All the best :)
