Ray optics and optical instruments are essential topics in physics that deal with the behavior of light rays as they interact with various optical elements.
Ray Optics:
Ray optics, also known as geometrical optics, is a branch of optics that describes the behavior of light using rays. It is based on the assumption that light travels in straight lines and does not exhibit wave-like properties such as diffraction and interference.
Key principles of ray optics include reflection, refraction, dispersion, and the formation of images by mirrors and lenses.
Optical Instruments:
Optical instruments are devices designed to manipulate light for various purposes, such as imaging, magnification, and measurement. Examples include mirrors, lenses, microscopes, telescopes.
