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.
Is torch both source of light and heat?
Yes, a torch can be a source of both light and heat. The light is produced by the flame or the electric bulb, while the heat is generated by the burning fuel or the electric components.
What source of light is shown in the diagram?
The diagram shows an incandescent light bulb as the source of light. It consists of a tungsten filament that emits light when an electric current passes through it, causing it to heat up and glow.
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.
How does light travels from a light source?
Light travels from a light source in the form of electromagnetic waves. These waves consist of alternating electric and magnetic fields that propagate through space. The speed of light in a vacuum is about 300,000 kilometers per second.
Why is the sun an extended source of light?
The Sun is considered an extended source of light because it emits light from a large surface area rather than a single point. This means that the light it produces comes from various points on its surface, creating a more diffuse illumination. As a result, sunlight is not concentrated in a single direction but spreads out over a wide area, contributing to its classification as an extended source. This characteristic affects how shadows are cast and how light interacts with objects on Earth.
Is an electric light a light source?
Yes.
What is an extended source of light?

Is an electric light bulb a natural or artificial source of light?
yes
A set of Christmas tree lights is a light source is it true?
noooooooooooooooooooooo . Of course a set of Xmas lights is a light source. Any electric light is a light source.
What is the thing called that provides light for a microscope?
Light source, can be mirror or electric light.
Is torch both source of light and heat?
Yes, a torch can be a source of both light and heat. The light is produced by the flame or the electric bulb, while the heat is generated by the burning fuel or the electric components.
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.
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..
What is the source of light in Norway?
Mostly hydro electric power
What is unnatural light source?
An unnatural light source is any source of light that is not produced by natural occurrences like the sun or a fire. Examples include electric light bulbs, neon signs, and LED lights.
Is lightning a light source?
Yes, lightning produces light, so it can be considered a natural light source. However, it is not a constant source of light like the sun or a light bulb.
