$\underline{\mathfrak{\red{Answer}}}$

In the last century, most scientists thought light did travel in tiny waves fractions of millimetre long, rather than in bullet-like particles. Now they agree it can be both, and it is best to think of light as vibrating packets of energy.

Answer 2

Explanation:

Yes light travels in wave through the properties of diffraction , interference , polarization . The whole wave optics teaches us the wave nature of light.
