According to NASA, Mars receives less than half the sunlight that would have been cast on Earth, due to an inverse square relationship between the intensity of incident sunlight and the distance from the sun, or I ∝ 1⁄d² where I is the intensity and d is the distance.
|“||I ∝ 1⁄d²||„|
| — Intensity is an inverse relationship|
to the square of the distance
- I — intensity
- d — distance from sun (light source)
- (Note: ∝ is a proportionality symbol, as opposed to an equality symbol, it is a way to compare information or establish a relationship between two variables.)
Even though Mars has a thinner atmosphere, due to the phenomenon described herein, it still does not receive the same intensity of light as the Earth.
The actual formulaEdit
- Ir = intensity at specified distance
- Is = intensity at center of source
- r = radius or distance from center of source
- approximation by a point light source with uniform light in all vectors
- no obstructions or forces impeding or deflecting light transmission
