Optics

Course Description

This course introduces the four fundamental areas of optics: geometrical optics, interference, diffraction, and polarization. It emphasizes calculations and basic concepts, making it a good starting point for students to learn more about this important field of physics.

1. Geometrical optics is the study of light propagation using rays. It is based on the principle that light travels in straight lines in a vacuum. Geometrical optics is used to design lenses, mirrors, and other optical devices.
2. Interference is a phenomenon that occurs when two or more light waves overlap. It can produce constructive or destructive interference, depending on the phase relationship between the waves. Interference is used in a variety of optical devices, such as thin films and interferometers.
3. Diffraction is a phenomenon that occurs when light waves pass through a narrow opening or around a small obstacle. It causes the light waves to spread out or diffract. Diffraction is used in a variety of optical devices, such as gratings and holograms.
4. Polarization is a phenomenon that describes the orientation of the electric field of a light wave. Polarized light can be used in a variety of optical devices, such as liquid crystal displays and sunglasses.
