The difference between artificial light and natural light Is there any difference between artificial

1. The light source is different.

The basic light sources of artificial light are floodlights, flashlights, and spotlights, which are the light produced by people with the help of external objects.

The main source of natural light is the sun, which usually includes direct sunlight from the sun, cloudy days.

Diffuse scattered light from the sky on rainy and snowy days, as well as moonlight and starlight.

2. The influencing factors are different.

Artificial light is mainly affected by the type of light source and the method of lighting, while natural light is affected by weather, shelter, time, season, etc.

3. The characteristics are different.

Artificial light has the characteristics of continuous illumination, unlike the natural light emitted by the sun, which comes and goes as the sun rises and sets, so artificial light has more flexibility and creative space than natural light, and it can make shooting everywhere. However, artificial light is affected by the light source, and the irradiation range is limited, so it is necessary to adjust the irradiation range of the light source through the light plate.

Compared with artificial light, natural light lacks the characteristics of flexibility and maneuverability, and cannot be arbitrarily adjusted and controlled by photographers, but the range of natural light can be extended indefinitely, and over time and the change of weather, the color and atmosphere produced are beyond the reach of artificial light.

Natural light allows for photosynthesis. Natural light: Visible light that exists in nature, such as sunlight, fire, lightning flashes, is usually produced by high temperatures and has a wide spectrum of light.

Artificial light: the light generated by artificially designed and manufactured instruments and equipment, such as fluorescent lamp light and lasers.

1. The reasons for its formation are different: natural light is emitted by processes such as the fusion of the sun's inner core. Artificial light, most of which is tungsten filament, is emitted by heating to a very high temperature.

2. The source of light is different: the source of natural light is the sun or the moon. The light source of artificial light is an artificial light wave.

3. Different spectral range: natural light has a wider spectral range. Artificial light is shorter.

That's right, light is electromagnetic waves, from radio, microwave, infrared, visible light, ultraviolet, Roentgen rays, rays, they all have different mechanisms, but the essence is the same. They satisfy the same law of ascension, (Maxwell's theory of electromagnetism). However, when the frequencies are different, there are also different characteristics, such as refractive index, velocity in the medium, etc.

Sunlight and flashlights, the reason for the production of light is different, but there is really no difference between light.

All light in a vacuum has the same speed of light, so you take the flashlight mountain mold barrel in the light"In a vacuum, along a straight line"The distance of running for a year is also a light year of base only old ().
