Is a torchlight a natural source of light?
Torch light is NOT a natural source of light. It is an Artificial Source of light generated by the electrical energy. In this the electrical energy is being transformed into Light energy.
What is the source of heat and light for all the plants?
The sun is the source of heat and light for plant-life.
Is tube light a cold source of light?
yes
Is a window a light source?
no
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.
Where does light from an object come from?
the object is reflecting the light from anoher source unless it producs it
How do you explain light source to your 7 year old?
Well I'm sure he knows what light is, so they need to understand what a source is. You tell him/her that a source, is where things come from: embellish however seems good. And of course, a light source, is where light comes from. Some examples: the sun, a light bulb or LED (light emitting diode), or anything that emits photons.
What type of wavefront will emerge from a point source and distant light source?
For a point in space (or from a distant light object), spherical waves are emitted. From a point source on the surface of a liquid, circular waves will come out. In both cases the source will be the focus of the emitted waves.
An object that gives out light is it a light source or it is a light energy?
It is a light source.
Do compound microscope uses light for illumination?
Yes, compound microscopes use light for illumination. Light is typically directed through the specimen being observed to enable magnification and visualization of the object on the slide. The light source can be built into the microscope or come from an external source.
What is a light source?
The Sun is a light source Something that makes light.
Is a computer screen a light source or a light reflector?
light source
Is a lightning a source of light?
It is certainly a source of light but it is not a practical, usable source.
Is a traffic light a light reflector or light source?
A traffic light is a light source as it emits light to signal drivers when to stop, slow down, or go.
How can an electric bulb be considered as an extended source of light an as point source of light?
Either, depending on the situation. If you look at it from far away, the light seems to come from a single direction, and can be simplified as a point-source. If you are very close, the light comes from different directions, and such a simplification is no longer correct.
What is a luminous light source?
Luminous light is a light source but another name for it.
What does a light source do on microscope?
It
