As light travels further from its source, its intensity decreases with the square of the distance traveled. This is known as the inverse square law, meaning the intensity of light diminishes drastically as distance increases. This is due to the spreading out of light over a larger area as it travels further.

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.
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.
Why does the intensity of light decrease as the distance from the source increases?
The intensity of light decreases with distance due to the spreading out of light waves over a larger area. This phenomena is a result of the inverse square law, which states that the intensity of light is inversely proportional to the square of the distance from the source. As light spreads out, it becomes less concentrated, resulting in a decrease in intensity.
How does light intensity vary with distance form the source?
Light intensity decreases as distance from the source increases. This is because light spreads out in all directions as it travels, causing the same amount of light to be distributed over a larger area the further it travels. This decrease in light intensity follows an inverse square law, meaning that the intensity decreases proportionally to the square of the distance from the source.

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.

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)
What happens when a flashlight moves father away from an object?
As the flashlight moves farther away from an object, the intensity of the light reaching the object decreases. This will result in the object appearing dimmer or less illuminated as the distance between the object and the flashlight increases. The inverse square law describes how the intensity of light diminishes with distance.
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.
What is the effect of varying the intensity of light on a sphere's surface?
The effect of varying the intensity of light on a sphere's surface is that it will change the brightness and shadow patterns on the sphere. Higher light intensity will result in a brighter appearance and sharper shadows, while lower light intensity will make the sphere appear dimmer with softer shadows.
Intensity of light depends on the?
The intensity of light depends on the amplitude of the light waves, which represents the strength or power of the light wave. The intensity is also affected by the distance the light has traveled from the source, which can cause the light to spread out and decrease in intensity. Additionally, materials through which light passes can affect its intensity through absorption or scattering.
If cardboard were four times the unit distance away from the bulb how much would the light falling on the cardboard be?
The intensity of light falling on the cardboard would be 1/16th of the original intensity because the intensity of light is inversely proportional to the square of the distance from the source.
