It's measured in light-years (or parsecs)

which is trillions of miles.

What is the size of the shadow and the distance of the object from the light source when a shadow is formed?

If you are using a point light source, the shadow's size is the object's size divided by the distance from the light source to the object multiplied by the distance from the light source to the shadow.


Is there a relationship between the distance of the light source and the object?

Yes, there is a relationship between the distance of a light source and an object. The intensity of light decreases with increasing distance from the light source following the inverse square law. This means that the further the object is from the light source, the dimmer the light it will receive.


What happens to the light intensity if you half the distance to the source?

The light intensity increases by a factor of four when you half the distance to the source. This is known as the inverse square law, where light intensity is inversely proportional to the square of the distance from the source.


If the distance from the light source is tripled how much does the light intensity change?

The light intensity decreases by a factor of nine when the distance from the light source is tripled. This relationship is governed by the inverse square law, which states that the intensity of light is inversely proportional to the square of the distance from the source.


What is the equation that relates the intensity of light to the power of the light source and the distance from the source?

The equation that relates the intensity of light to the power of the light source and the distance from the source is known as the inverse square law. It is expressed as: Intensity Power / (4 distance2)


Why does intensity decreases as the distance from the light source increases?

Intensity decreases as the distance from a light source increases due to the spreading out of light waves over a larger area. This leads to light being more dispersed and less concentrated at a greater distance from the source. The inverse square law dictates that the intensity of light decreases proportionally to the square of the distance from the source.


How is the intensity of light and distance related?

The intensity of light decreases as distance from the source increases. This relationship follows an inverse square law, meaning that if you double the distance from the source of light, the intensity decreases by a factor of four.


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 the distance between the light and reflection called?

I'm not entirely sure, but I think it's the angle of reflection.


What is the effect of distance on the brightness of a light bulb?

The brightness of a light bulb decreases as the distance from the light source increases because the light spreads out over a larger area. This phenomenon is known as the inverse square law, where the intensity of light diminishes proportionally to the square of the distance from the source.


How is the brightness of light determined?

The brightness of light is determined by the intensity of the light source and the distance from the source to the object being illuminated. The closer the object is to the light source and the more intense the light, the brighter the light will appear.


How does the size of the shadow vary with the distance between the light source and the object?

The size of the shadow increases as the distance between the light source and the object increases. This is because the light rays diverge further apart as they travel a greater distance, resulting in a larger shadow being cast. Conversely, if the light source is closer to the object, the shadow will be smaller.
