Physical Science Light Ch. 1-4 quiz
18
corpuscles: particles that make up light and travel through a vacuum like little bullets.
umbra: black central portion of a shadow.
Newton: scientist convinced of straight-line, particle-like nature of light.
self propagation: term meaning that light does not need a medium for propagation.
Louis de Broglie: scientist who advanced theory that allowed for a wave motion of particles of matter.
incident ray: portion of a light ray that falls on a surface.
reflected ray: portion of a light ray that is reflected off a surface.
specular reflection: reflection of light from a perfectly smooth, highly polished surface.
diffuse reflection: reflection of light from a rough or unpolished surface.
reflection factor: the ratio of the amount of light reflected from a surface to the amount of incident light.
virtual image: the image of a point in a plane mirror.
radius of curvature: the distance from the mirror to the center of curvature.
refraction: the bending of light as it passes into a transparent material of a different optical density.
index of refraction: ratio of the velocity of light in a vacuum to the velocity of light in a material.
optical prism: solid piece of glass bounded by three rectangular and two triangular surfaces.
angle of deviation: angle formed by extending the path of the incident portion of the ray and the refracted portion.
lens: a piece of glass that has either two curved surfaces, or one curved surface and a flat surface.
converging lens: lens which is thicker at the center
diverging lens: lens which is thicker at its edges.
chromatic aberration: effect of dispersion of white light by a lens.
achromatic lens: combination of two or more lenses that correct chromatic aberrations.
