a lantern? I'm sorry if this is wrong.
The antumbra is the region of a shadow that is partially shaded and partially illuminated by a light source, such as during a solar eclipse when the moon does not entirely cover the sun. It is the area where the light source is not completely blocked, creating a dimmer shadow than the umbra.
Luminous flux is the total amount of light emitted by a source in all directions, while lumens measure the amount of light that is actually perceived by the human eye. The higher the luminous flux or lumens, the brighter the light source will appear to us.
Callisto, one of Jupiter's moons, is about 481 million miles away from the sun. In terms of light-years, it is roughly 0.000005 light-years from the sun.
In physical terms - to the ends of the Universe. In practical terms - to the edge, where something more massive has a greater influence. In "our" terms, about 2 light years from the Sun (But all depends in which direction you are looking (thinking).
I will not be able to reach the sun in terms of light years as it is within our own solar system. However, light from the sun takes about 8 minutes to reach Earth so you could say it would take about 8 minutes in terms of light years to "reach" the sun.
when objects get lighted from other source of light it is known as illumination
The terms light source and illuminant have precise and different meanings. A light source is a physical emitter of radiation such as a candle, a tungsten bulb, and natural daylight. An illuminant is the specification for a potential light source. All light sources can be specified as an illuminant, but not all illuminants can be physically realized as a light source.
The conversion factor from lux to watt depends on the efficiency of the light source. It can be used to determine the power consumption of a light source in terms of lux by multiplying the lux value by the conversion factor to get the power consumption in watts.
Phototropism refers to a plant's response to light, where the plant grows toward or away from a light source.
Flame-like light bulbs differ from traditional light bulbs in appearance by resembling a flickering flame, while traditional light bulbs have a standard bulb shape. In terms of functionality, flame-like light bulbs are designed to mimic the look of a flame and create a cozy ambiance, while traditional light bulbs provide consistent and uniform lighting.
In terms of physics, No (because light "interferes" with light from another "source" , creating interference patterns). However "lighting bugs" DO use light to attract a mate!
Lux and nits are both units of measurement for brightness, but they measure different aspects of light. Lux measures the amount of light that falls on a surface, while nits measure the brightness of a light source itself. In simpler terms, lux measures how bright the light is on a surface, while nits measure how bright the light source itself is.
Luminous objects are sources that emit light, while illuminated objects are those that reflect or scatter light from a different source.
The power of light equation is P I A, where P is power, I is intensity, and A is area. This equation shows that the power of light emitted by a source is directly proportional to the intensity of light and the area over which the light is spread. In simpler terms, the more intense the light and the larger the area it covers, the greater the power of light emitted.
The term "polar curve", in relation to the subject of illumination refers to the spread of light from a source. If the curve is weak, then little illumination is provided, whilst the opposite is true for a strong curve.
In Australia, the word Christmas is simply known as Christmas. There are no other terms for this celebration of Christ's birth.
A lumen measures the total amount of visible light emitted by a source in all directions. On the other hand, a candela measures the intensity of light emitted in a specific direction. In simpler terms, a lumen tells you how bright a light source is overall, while a candela tells you how bright the light appears in a particular direction.
