Expert Answer:

Dear student
Light is a region of spectrum of electromagnetic waves which can be seen by the normal human eye. It has wavelengths between 400-760 nm. The color of the light is related to its wavelength. It travels through empty space at 3 x 108 m/s and shows the properties of reflection, refraction, diffraction, polarization etc.
We hope this clarifies your doubt.
