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.
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.
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 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 describes the effect of distance on the intensity of light?
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.
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 other feature of light other than intensity will also change with distance from the canopy?
The quality of light, such as its color spectrum, will also change as it passes through a canopy and with distance from it. This change is due to absorption and scattering by the leaves, resulting in different wavelengths dominating at various distances.
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.
How to calculate light intensity in a given environment?
To calculate light intensity in a given environment, you can use a light meter to measure the illuminance in lux or foot-candles. This device measures the amount of light reaching a surface. The formula to calculate light intensity is: Light Intensity Illuminance x Distance2 Where: Illuminance is the amount of light falling on a surface in lux or foot-candles Distance is the distance between the light source and the surface By using this formula, you can determine the light intensity in a specific environment.
