The study of light and its behavior as it interacts with matter. It focuses on phenomena like reflection, refraction, and diffraction, which are explained using geometrical principles.

The physical characteristics and properties of light. It's described by different models, including the wave model and the particle model.

Huygens's wave theory of light cannot fully explain phenomena like shadows, interference, and polarization, which are better explained by the electromagnetic theory of light.

Huygens's theory suggests that light needs a medium to travel, but experiments show that light can travel through a vacuum (like space).

The emission of electrons from a metal surface when light (photons) hits it.

Plank's theory explains how light interacts with matter, including how it is absorbed, scattered, emitted, and causes the photoelectric effect.

Light can be absorbed by a material, meaning the material takes in the light energy.

Light can be scattered by a material, meaning the light changes direction as it interacts with the material.

Light can be emitted by a material, meaning the material releases light energy.

The minimum energy required to remove an electron from a metal surface.

The energy an electron gains after absorbing a photon, allowing it to escape the metal.

The energy absorbed by an electron from a photon.

A tiny particle of light that carries energy.

The phase difference between two waves is proportional to the optical path difference, with a constant of proportionality of 2π/λ.

Snell's Law describes the relationship between the angles of incidence and refraction when light passes from one medium to another. It states that the ratio of the sines of these angles is equal to the ratio of the indices of refraction of the two media.

Every point on a wavefront can be considered as a new source of spherical waves that propagate outwards at the same speed in the medium.

Optical Path Difference (OPD) refers to the difference in distances traveled by two light waves from the source to a specific point. It's calculated by multiplying the difference in path length by the refractive index of the medium.

The angle between the incident ray and the normal to the surface at the point of incidence.

The angle between the refracted ray and the normal to the surface at the point of refraction.

The ratio of the speed of light in vacuum to the speed of light in a medium.

When light passes from one medium to another, its frequency remains the same, but its wavelength changes.

The process by which light bends as it passes from one medium to another, due to a change in speed.

The bending of light around an obstacle or through an opening.

The change in direction of a light ray when it bounces off a surface.
