What does laser stand for and what does it mean?
It stands for Light Amplification by Stimulated Emission of Radiation, and it means that light is strengthened to form a high-intensity ray of light.
What is the relationship between the size of the shadow and the distance of the object from the light source?
The relationship between the size of a shadow of an object and the distance of light source from the object is indirectly proportional. A short distance will make the shadow big while making the distance long will reduce the size of the shadow.
Is light a renewable resource of energy?
Light IS energy; it is not a SOURCE of energy. You can convert one form of energy into another, if you need to.
What is the difference between light and shadow?
light is a form of energy an object which has its own light is called a source of light where as shadow is the picture of a body formed when light is blocked by the opaque bodies.
How does electric field intensity form?
due electrostatic force
Is comet a source or form of light?
A Source with form of light like the sun.
As photons travel further form the source of light theintensity of the light?
decreases in proportion to distance from the object squared. A good example in the link below.
What is the HID Flashlight?
HID means High Intensity Discharge and is a modern form of lighting in which a compact arc is used as the source of light. They are more efficient that halide lamps.
Can a rainbow form without the light of the sun?
No it is not a light source but a light trick a light source produces light
What is source light?
A light source is a form of energy produced by heat.
Is white paper a form of a light source?
No

What do you call an area where direct light form a light source is blocked by object?
A shadow.
What is light absorption?
Absorption is the reduction of intensity of any form of radiated energy as a result of energy conversion in a medium.
What is the verb form of intensity?
The verb form of intensity is intensify. As in "to intensify something".
What is the distance form earth to star measured by?
light years
How is shadow form?
From the absence of light. Shadow is form from an opaque or translucent object blocking a light source (since light travels in a straight line).
