SCIENCE QA REVIEW

2ND QUARTER, 10-DOCILITY

QuestionAnswer
is a form of energy that allows you to see the things around you. Light
transport of energy Wave
Portion of Matter Particle
Light consisted of streamers emitted by the eye Plato
Light originated from luminous bodies in a form of very fine particles Pythagoras
Light is composed of high speed waves of some sort Empedocles
Explains that light has a wave motion which starts from a vibrating body and is transmitted at the high speed. Wave theory
Aethers Since light can pass through a vacuum, he explained that light may travel through a medium known as ethers, a mysterious substance which is not air Christiaan Huygen's principle
Light consists of tiny particles of matter emitted by a source that travel only in straight lines called rays Isaac Newton's corpuscular theory
Bouncing off of light rays when hitting a smooth surface Reflection
the bending of light rays as they pass from one medium to another, thereby changing the path of the rays Refraction
Observing that when light from a single source is split into two beams, and the two beams are then recombined, the combined beam shows a pattern of light and dark fringes Interference by Thomas Young
Quantum theory of Light Light is composed of bundles of wave energy called photons. This finding supported Planck’s Theory. Albert Einstein's Photoelectric Effect
the emission of electrons by a metal surface when it is irradiated by light or more-energetic photons Photoelectric Effect
All light comes from a luminous source Luminous Object
Those objects that cannot emit their own light. Non-luminous objects
High-temperature objects give off hot light or incandescent light. Incandescent light
is cold light. It is emitted without heat. Some animals give out this type of light Luminescent light
emission of electromagnetic radiation, usually visible light, caused by excitation of atoms in a material, which then reemit almost immediately Fluorescence
emission of light from a substance exposed to radiation and persisting as an after glow after the exciting radiation has been removed Phosphorescence
production and emission of light by a living organism Bioluminescence
refers to the manner in which an electromagnetic wave transfers its energy from one point to another. Propagation of light
an object that permit the passage of light Transparent
objects that don’t allow light to pass through, but a shadow is produced. Opaque
an object that both the characteristics of opaque and transparent Translucent
separation of visible light into its different colors based from their wavelengths and frequencies Dispersion
Property of certain types of waves that describes the orientation of their vibrations Polarization
A ray of light approaches a surface and the light ray bounces back Law of reflection
ray that strikes the surface Incident ray
ray that rebounds from the surface reflected ray
Line perpendicular to the surface at the point of incidence Normal
A group of parallel rays strikes a smooth flat surface Specular reflection
A group of parallel rays strike a rough surface Diffuse reflection
A mirror with a flat reflective surface Plane mirror
A mirror which has the shape of a piece cut out of a spherical surface Spherical mirror
image formed in front of the mirror Real image
image formed at the back of the mirror Virtual image
