There are two main formulas used to measure light intensity: luminous flux and illuminance. Luminous flux measures the total amount of light emitted by a source, while illuminance measures the amount of light that falls on a surface.
The light intensity formula is I P/A, where I is the intensity of light, P is the power of the light source, and A is the area over which the light is spread. This formula can be used to measure the brightness of a light source by calculating the intensity of the light emitted per unit area. The higher the intensity value, the brighter the light source is perceived to be.
Lumens measure the total amount of light emitted by a source, candela measures the intensity of light in a specific direction, and lux measures the amount of light that falls on a surface. Lumens indicate overall brightness, candela measures brightness in a specific direction, and lux measures brightness on a surface.

Brightness refers to the subjective perception of how light appears to the human eye, while intensity is a measurable physical quantity that represents the amount of light energy emitted. Brightness is influenced by factors such as the intensity of light, the surface area it illuminates, and the sensitivity of the human eye. Intensity, on the other hand, is a quantitative measure of the amount of light energy present. The perception of light is affected by both brightness and intensity, as they work together to create the overall visual experience.
Lux and candela are both units of measurement for light intensity, but they measure different aspects of light. Lux measures the amount of light that falls on a surface, while candela measures the brightness of a light source in a specific direction. Lux is used to determine the brightness of an illuminated area, while candela is used to measure the intensity of a light source. In essence, lux measures the light that is received, while candela measures the light that is emitted.

No telling. Volts are a measure of electric potential. Lumens are a unit for light intensity. Different bulb types with the same input voltage will yield different lumens out.

Candela measures the intensity of light emitted in a specific direction, lumens measure the total amount of light emitted by a source, and lux measures the amount of light that falls on a surface. Candela is used for directional light sources like flashlights, lumens for overall brightness of a light source, and lux for the brightness of light on a surface.
Yes, the brightness of light can be measured using various instruments. The most common unit for measuring brightness is the lumen, which quantifies the total amount of visible light emitted by a source. For more specific measurements, tools like photometers and light meters can assess light intensity in different conditions. Additionally, brightness perception can vary depending on factors such as distance and the observer's eyes.
Magnitude refers to the size or amount of a quantity, often used in scientific contexts to describe measurable properties such as brightness or seismic strength. Intensity, on the other hand, refers to the strength or power of a particular effect or phenomenon, often relating to how that quantity is perceived or experienced, such as the loudness of sound or the brightness of light as perceived by the human eye. While magnitude provides a numerical measure, intensity conveys the quality of experience associated with that measure.
The measure of a star's brightness is its magnitude. A star's brightness as it appears from Earth is called its Apparent Magnitude.Star's brightness is measured by there magnitude.
Magnitude typically refers to the size or extent of something, while intensity refers to the degree or amount of force or energy involved in a situation. In the context of natural disasters, magnitude is used to measure the size of events like earthquakes, while intensity relates to the impact felt by people and structures at specific locations.
