The terms light source and illuminant have precise and different meanings. A light source is a physical emitter of radiation such as a candle, a tungsten bulb, and natural daylight. An illuminant is the specification for a potential light source. All light sources can be specified as an illuminant, but not all illuminants can be physically realized as a light source.

What is the difference between light producer and light reflector?
Source light is light coming directly from a light source/emitter (i.e. a light bulb, the sun, stars, etc.). Reflected light is light coming indirectly from the light source/emitter. That could be reflected, refracted light, etc.
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.
What is the difference between a ray of light and a beam of light?
A light beam or beam of light is a narrow cone of light energy radiating from a small source. In optics, a ray is an idealized narrow beam of light.
What is the difference between a black light and a regular light bulb?
The black light is in jail
What is the difference Between Light energy and Radiant Energy?
Light is light. Radiant is Radiant.
What is the difference between a light microscope and a TEM?
source of illuminatio is light in first and beam of electrons in second
What is the difference between light and reflected light?
Source light is light coming directly from a light source/emitter (i.e. a light bulb, the sun, stars, etc.). Reflected light is light coming indirectly from the light source/emitter. That could be reflected, refracted light, etc.
Difference between shadow and reflection?
A shadow is the absence of light, a reflection is just that, the reflection of light. So a shadow comes from blocking a light source, a reflection comes from the bouncing of light of one source and on to another
Is the brightness of glow in the dark materials affected by the light source used to make them glow or only by the intensity of the light Does the light source?
It depends on the luminescence of the materials. I see no difference between "the light source" and "the intensity of the light". Please restate and/or clarify the question.
Why is an extended source used in newtons ring experiment?
extende source is required to get nearly parallel rays of light

What makes a dc bulb different from an ac bulb?
The voltage source that is applied to them is the difference between AC and DC light bulbs.
What is the difference between a shadow formed by a point source of light and a extended source?
The shadow formed by the point source of light has a screen blocking it. So it is very precise and only forms an umbra. Whereas the other is not as precise and forms an umbra and a penumbra.
What is the difference between a light source and a reflector provide examples for each?
A light source generates and emits its own light. A reflector reflects light (i.e. light bounces off of it) from another source. Examples of light sources: The sun, the stars, a lightbulb, a flame, a red-hot piece of metal. Examples of reflectors: The moon, the planets, the ground lit by the sun.
