Illumination involves a source of light being emitted.

To have visibility, the human eye requires illumination of light for things to be seen.

Visibility is the state of being seen. To be visible you must have a level of illumination--a source of light.

Illumination refers to the amount of light in a specific area, while visibility is the ability to see clearly. Higher illumination can improve visibility by reducing shadows and increasing contrast, making objects easier to see. Low illumination can reduce visibility by making objects appear dim and harder to distinguish.

What is the condition of illumination?

Illumination refers to the amount of lighting in a space. It is important for visibility, safety, and mood-setting. Adequate illumination can improve productivity and reduce strain on the eyes.


What is a flashlight for?

The primary purpose of a flashlight is illumination in dark areas to provide visibility to the user.


What is the illumination of a surface by a light source directly proportional?

The illumination of a surface by a light source is directly proportional to the intensity of the light source and inversely proportional to the square of the distance between the light source and the surface. This relationship is described by the inverse square law of illumination.


How does the illumination on a surface vary with distance from a light source?

The illumination on a surface decreases as the distance from the light source increases. This is because light spreads out as it travels, leading to a decrease in light intensity the further away from the source. The relationship between illumination and distance follows an inverse square law, where doubling the distance results in a fourfold decrease in illumination.


What is specific illumination?

Specific illumination refers to the amount of light that falls on a specific area or object. It is measured in lux or foot-candles and is important for tasks that require detailed vision, such as reading or working on small objects. Different activities require different levels of specific illumination for optimal visibility.


What is the opposite of light?

The opposite of light is darkness. Light represents illumination and visibility, while darkness represents absence of light and lack of visibility.


What is the function of the illumination intensity knob?

The illumination intensity knob controls the brightness of the light source in a microscope. By adjusting this knob, you can increase or decrease the amount of light that shines on the specimen, helping to improve visibility and contrast for better microscopy observations.


What made the darkness disappear?

The rising sun or turning on a light can make darkness disappear by providing illumination and increasing visibility in a given space.


What are the principles of illumination?

The principles of illumination in design include providing adequate lighting for visibility and functionality, creating a visually appealing atmosphere, and reducing glare and shadows. It involves considering factors such as light intensity, color temperature, and distribution to enhance the overall environment.


What is difference between ambient occlusion and global illumination?

Ambient occlusion is a "fake" global illumination technique, its faster and it looks similar, however it is a very crude approximation to full global illumination


Why would want to reflect light?

Reflecting light can help increase visibility, enhance the illumination of a space, or redirect light for better distribution. It can also be used for decorative purposes or to create a specific ambiance in a room.


When driving in foggy weather, if the fog is so thick cannot see ahead all you shold :?

Use low-beam headlights. When visibility is restricted, a driver's natural tendency is to activate the high-beam headlights. When driving in fog, this further impairs visibility because the high-beam illumination reflects off of the fog and back at your vehicle.
