Science

A body of knowledge, often formulated as laws and theories, based on the collection of data through observation and experiment.
physics: optics

PHYSICS: OPTICS

Optics: the scientific study of light and vision; its various applications include lenses, microscopes, lasers and fiber optics.

wave

wave

Oscillation caused by a disturbance; as it propagates through a medium (mechanical waves) or a vacuum (electromagnetic waves), it carries energy.

electromagnetic spectrum

electromagnetic spectrum

Electromagnetic waves that are classified in ascending order of energy (frequency); they propagate at the speed of light (300,000 km/s).

color synthesis

color synthesis

Technique of generating color by combining light rays or subtracting them to obtain a colored image.

vision

vision

Ability to perceive shapes, distances, motion and colors; it is related to light rays and varies depending on the degree of sensitivity of the eye.

lenses

lenses

Transparent pieces of material (usually glass) that cause light rays to converge or diverge to form a sharp image (eyeglasses, microscopes, telescopes, cameras).

pulsed ruby laser

pulsed ruby laser

Device that produces a thin and very intense colored light beam; its various applications include fiber optics, manufacturing and surgery.

telescopic sight

telescopic sight

Optical instrument mounted on a rifle or a measuring device to increase accuracy.

prism binoculars [1]

prism binoculars [1]

Optical instrument made up of two identical telescopes, one for each eye; it magnifies both near and distant objects.

prism binoculars [2]

prism binoculars [2]

Optical instrument made up of two identical telescopes, one for each eye; it magnifies both near and distant objects.

magnifying glass and microscopes

magnifying glass and microscopes

Optical instruments used to magnify the image of a near object; they range in strength from low (magnifying glass) to strong (microscope).
