What is the difference between a shadow formed by a point source of light and a extended source?
A shadow formed by a point source of light has distinct, sharp edges due to the single light source, while a shadow formed by an extended source has softer, less defined edges because light is coming from multiple directions. The point source produces a single, intense shadow, while the extended source creates a more diffused shadow.
ShadoW formed by an extended source?
A shadow formed by an extended source appears fuzzy with indistinct edges due to partial blocking of light from multiple directions. The shadow's edges may exhibit a gradient of light intensity instead of a sharp boundary seen in shadows from point sources.
Can you explain why the moon is not a source of light?
The moon is not a source of light because it simply reflects the suns light, therefore it is not a direct source of light
Is candle flame a source of light?
The flame of a candle is a source of light.
What would happen if the sun was the only source of light?
It is the only source of light!
What is an extended source of light?
An extended source of light refers to a light source that is not a point source, meaning it has a finite size and emits light over an area rather than from a single point. Examples include fluorescent tubes, incandescent bulbs, and the sun.
What will happen if a point source is used instead of extended source in Newton's ring experiment?
The rings may formd but the lack of intensity of light,the dark and light rings are not vissiable very well..

Why is an extended source used in newtons ring experiment?
extende source is required to get nearly parallel rays of light
How can an electric bulb be considered as an extended source of light an as point source of light?
An electric bulb can be considered as an extended source of light when the light from the bulb spreads out in different directions, illuminating a larger area. On the other hand, an electric bulb can be considered as a point source of light when the light emitted can be assumed to originate from a single point within the bulb, leading to parallel light rays.

Why extended source is used in the newtons ring experiment?
An extended source is used in the Newton's ring experiment to ensure that the light incident on the glass plate is coherent and uniform. This helps to produce clear and sharp interference fringes, which are essential for accurate measurements of the radius of curvature of the lens and the wavelength of light.
What is the energy pathway for a phosphorescent light source?
Phosphorescent light sources convert electrical energy into light energy through a process called phosphorescence. When the phosphor material in the light source absorbs energy from an external source, such as electricity, it temporarily stores this energy and then releases it as light over an extended period of time. This delayed emission of light is what gives phosphorescent materials their characteristic glow after the initial energy source is removed.
What did the light bulb do?
The light bulb revolutionized lighting by providing a reliable and efficient source of artificial light. It allowed for extended hours of productivity, enhanced safety, and improved quality of life by illuminating homes, streets, and workplaces.
An object that gives out light is it a light source or it is a light energy?
It is a light source.
Is a computer screen a light source or a light reflector?
light source
What is a light source?
The Sun is a light source Something that makes light.
