What is the shape of wavefront in light diverging from a point source?
The shape of a wavefront in light diverging from a point source is spherical. This means that the wavefront expands outward in all directions from the source, creating a series of concentric spheres.
What is meant by light rays being divergent?
When light rays are divergent, it means they are spreading outwards in different directions from a single point of origin. This happens when the light source is far from the object being illuminated, causing the rays to diverge as they travel towards the object.
What is the difference between giving off light and reflecting light?
Giving off is emitting it and reflecting light is reflecting it
What means to gives out light?
To give out light means to emit photons or electromagnetic radiation in the visible spectrum, making an object or source visible to the human eye. Light can be produced naturally (such as sunlight) or artificially (such as light bulbs or LEDs).
What is it called when you have an uninterrupted path from a power source to a light bulb?
It is called a closed circuit. This means that the electricity can flow continuously from the power source to the light bulb and back again.

What is a lumen of light?
A lumen of light is a measurement of visible light. It means the brightness of light and can vary depending on the light source.
Is there a relationship between the distance of the light source and the object?
Yes, there is a relationship between the distance of a light source and an object. The intensity of light decreases with increasing distance from the light source following the inverse square law. This means that the further the object is from the light source, the dimmer the light it will receive.
What is the meaning of turn on the light?
It means 'operate the light-switch so as to cause the light to illuminate'.
Is a light bulb a source of an electric current?
No. The term SOURCE means that it is a supply of electrical energy, and a light bulb does not supply electricity, it uses it. A battery, generator, fuel cell, or solar cell would be a source.
What is the shape of wavefront in light diverging from a point source?
The shape of a wavefront in light diverging from a point source is spherical. This means that the wavefront expands outward in all directions from the source, creating a series of concentric spheres.
Why does light get dimmer as you walk away from it?
As you move away from a light source, the amount of light that reaches your eyes decreases due to the spreading out of light waves. This phenomenon is known as the inverse square law, which states that the intensity of light diminishes inversely proportional to the square of the distance from the source. This means that the further you are from the light source, the less intense the light will appear.
What is light fixtures?
A fixture or device that holds a light in place by means of some sort of socket, that is connected to a power source.

What does it means when something has three shadows?
three different source of light from three different directions
What is the difference between giving off light and reflecting light?
Giving off is emitting it and reflecting light is reflecting it
