The "'cone of light "', or light reflex, is a visible phenomemon which occurs upon examination of the tympanic membrane with an otoscope.

By now they could see a helicopter beaming a cone of light onto the water, as well as other boaters pulling bodies on board.
13.
Microscopic analysis of ulexite also yields cones of light that clearly emerge from each grain that is thicker than 0.1 mm under the Bertrand lens.
14.
Because the cone of light focused on the sample gives rise to different angles of incident light, there is a broad range of interference patterns.
15.
When the eardrum is illuminated during an examination, a cone of light radiates from the tip of the malleus to the periphery in the antero-inferior quadrant.
16.
The principle is similar to focusing sunlight through a magnifying glass : The light can burn paper, but only where the cone of light comes to a point.
17.
In the breeze, the shade jerks around like a ghostly, demented bell; at night, the swaying cone of light turns the terrace into a stage for shadow dancing.
18.
However, a larger exit pupil makes it easier to put the eye where it can receive the light : anywhere in the large exit pupil cone of light will do.
19.
The photon detector is then located at some distance ( usually about 10 cm ) behind the radiator, allowing the cone of light to expand and form the characteristic ring-shaped image.
20.
The jets, as their name implies, moved rapidly, bursting from the tops of giant storm clouds in cones of light that widened as they flashed upward to heights of perhaps 20 miles.
