Probably that refers to the SPEED of light; and perhaps the speed of something else. Or speeds in general. A speed can be defined as a distance divide by a time, i.e., how much something moves in a second, or in a minute, for example.
A meter is the distance light travels in a vacuum in 1/299,792,458 seconds, so a centimeter is this distance divided by 100 and a millimeter is this distance divided by 1000.
Moons and comets appear to shine because of the light they reflect. Stars produce their own light.
Because it will appear larger, and it will thus (and also because its closer) appear brighter. Remember that the intensity of light perceived is proportional to the surface area of the emitter, and inversely proportional to the square of the distance to the emitter.
The distance light travels in a year is called light-year
A light-minute is the distance light travels in a vacuum in one minute's time. The distance of a light-minute is 11,176,943.8 miles or 17,987,547.5 km

If you are using a point light source, the shadow's size is the object's size divided by the distance from the light source to the object multiplied by the distance from the light source to the shadow.

thomas young carried out his (double slit experiment) where he discussed the interference of light waves using monochromatic light . the 2 slits act as 2 coherent sources which emit light with same amplitude frequency . interference fringes appear due to superposition of light . this experiment is also used to determine the wavelength of monochromatic light. from the relation y=wavelength*distance between 2 slits /distance between the 2 slits and the screen where the fringes appear . where y is the distance between 2 successive bright or dark fringes.
Sunlight is effectively "white light", and the yellow color is produced by the scattering of light by the atmosphere. This is easily seen near sunrise and sunset, where the additional atmospheric distance and angle make the Sun appear red.
Well because the moon is grey but the suns light shines on it from a distance so that's why its white
4085 is a pure number. A light year is a measure of distance whose numeric value depends on the units used. There is, therefore, no sensible answer to the question.
In vacuum, the distance would be roughly 11.2 million miles (rounded). It's never used as a unit of measure, so it doesn't have any particular name, and would be called simply "one light-minute". The distance from Earth to the Sun is about 81/3 of them.
A City by the Light Divided was created in 2004.
The tyndall effect is a result of scattering from colloids that are around the wavelength of light, this is why milk does not appear blue.
The lemon will appear black as there is no yellow light to be reflected.
As with any material or substance, the apparent color is merely the result of light wave frequencies which are reflected by said material or substance.
