The illumination on the surface would be reduced by a factor of four, thereforeif the distance from a light source is doubled, the illumination provided by the source is one fourth as great.

What is inverse square law and an example?
inverse square law is the law that states the intensity of the light, sound etc is directly proportional to 1/ distance squared meaning the further you are from the source the less intense the light etc will be. e.g. an object 1m away from a light source 1/1^2=1 , 2m 1/2^2= 1/4 and so forth
How do you know that the perimeter of a rectangle is directly proportional to its length?
The perimeter of a rectangle is given by the formula P = 2(l + w). It is clear that as the length, l, increases, the perimeter, P, increases, as well. We say, therefore, that P is directly proportional to l. If l is the length and b is width of a rectangle then, the perimeter P of the rectangle is 2(l + b) units. P = 2(l + b) P = 2l + 2b If have b as a constant then, 2b will be a constant. Now l is the varying quantity. Say 2b = K P = 2l +K Perimeter changes if the length of the rectangle changes. In particular, if the length increases the perimeter of the rectangle increases. Similarly, if the length decreases the perimeter also decreases. So, the perimeter is directly proportional to the length of the rectangle. Source: www.icoachmath.com In the most simplest explanation, the sum of both lengths, and both widths of the rectangle, IS the perimeter. So obviously the perimeter is directly proportionate to its length (and its width).
What does the inverse square law state?
any physical law stating that some physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity.
How do leaves orient themselves so that each blade is about 90 degree angle to the source of light?
the petiole is able to twist and turn in order to maintain this orientation to the sun and thus expose the blades of each leaf to maximum illumination.

Describe the relation between the size of your source and electric current?
The current drawn from a power source is directly proportional to the voltage of thesource, and inversely proportional to the resistance of the circuit between its terminals.There is no relationship between the current and the physical size of the source.
How position relates to gravity?
The distance between two masses is directly proportional to the gravitational force between them. For example, the further you are from Earth's surface, the weaker Earth's gravitational force is on you. Source: high school physics
What is a source of illumination?
Illumination=light, so a source of light Eg. lightbulb, moon, sun etc.

What is the position on the Earth's surface directly above the earthquake source?
epicenter
What is illumination in terms of light?
when objects get lighted from other source of light it is known as illumination
What is an earthquake's source called?
The source of an earthquake is called the hypocenter, the point on the surface directly above it is the epicenter.
What relationship between illumination and visibility?
Illumination involves a source of light being emitted. To have visibility, the human eye requires illumination of light for things to be seen. Visibility is the state of being seen. To be visible you must have a level of illumination--a source of light.
What is the function of the illumination intensity knob?
illumination intensity knob is a knob that changes the view source.
When are shadows form?
