Frequently Asked Questions
Q1 : What is the meaning of optics and waves?
A1 : Optics is the study of light and its uses. "Light" is electromagnetic radiation which can be detected by our eyes, ie electromagnetic radiation with wavelengths in the range ~400 nm - 700 nm (though often very similar ideas apply beyond both ends of this wavelength range).
