What is the unit for illuminance?
The unit for illuminance is the lux (lx). Lux is defined as one lumen per square meter. It is used to measure the amount of light that falls on a surface, indicating the brightness or intensity of light at that point. Lux is commonly used in lighting design, photography, and other applications where the level of light is important. **
What is the reason that the illuminance of a surface decreases by a quarter of its value when the distance to the light source is doubled?
The illuminance of a surface decreases by a quarter of its value when the distance to the light source is doubled because of the inverse square law. This law states that the intensity of light at a point is inversely proportional to the square of the distance from the source. When the distance is doubled, the light is spread out over four times the area, resulting in a decrease in illuminance by a factor of four. This is why the illuminance decreases by a quarter of its value when the distance to the light source is doubled. **

How do I calculate the illuminance at different distances if the measurement in lux is given at a distance of one meter from the light source?
To calculate the illuminance at a different distance from the light source, you can use the inverse square law. This law states that the illuminance is inversely proportional to the square of the distance from the light source. So, if the illuminance is given at one meter, you can calculate the illuminance at a different distance by using the formula: E2 = E1 * (d1/d2)^2, where E1 is the illuminance at one meter, d1 is the distance at which E1 is measured, E2 is the illuminance at a different distance, and d2 is the distance at which E2 is to be calculated. **
