Optics Formulas
Essential optics formulas for lenses, mirrors, refraction, and light behavior.
Brewster's Angle
Calculate the angle at which reflected light becomes fully polarized. Used in laser design and glare reduction.
Magnification Formula
Calculate how much a lens or mirror enlarges or reduces an image. Used in microscopy, photography, and telescope design.
Mirror Formula
Calculate image position and size for concave and convex mirrors. Essential for mirror design and ray optics problems.
Numerical Aperture Formula
Calculate the light-gathering ability of an optical fiber or microscope objective. Key to fiber optic and imaging design.
Snell's Law
Calculate how light bends when passing between materials. The fundamental law of refraction in optics.
Thin Lens Formula
Relate object distance, image distance, and focal length for thin lenses. Core formula for lens and camera design.
