Is shadow an example of matter?
No, shadow is not an example of matter. A shadow is an area where light is blocked by an object, creating a darkened silhouette. Matter refers to anything that has mass and occupies space, such as solids, liquids, and gases.
Why does the central part of the shadow or the umbra is darker than the penumbra?
The penumbra is the part of the shadow from which PART but not all of the lightsource is visible, so that region is partly but not fully illuminated.The umbra is the part of the shadow from which NONE of the light source is visible,so that region is not illuminated at all, not even a little.That's why.
What is a preumbra?
The sun shines light on both the moon and the Earth. When it shines light on one side of either one, they cast a shadow in space. During an eclipse, the shadow of either the moon or the earth gets cast on the other one. For example, during a solar eclipse the sun, moon, and earth have to be aligned Sun - Moon- Earth. The sun shines light on the moon and the moon's shadow gets cast on the Earth. The middle of the shadow where an observer can't see any light is the umbra. The sides of the shadow where you can see partial light is the preumbra.
When light passes at an angle from air to glass do the light changes direction due to refraction?
yes light changes its direction when it passes form air to glass due to refraction of light coz air has less density n glass is a solid so it has more density due to that when light goes form air to glass then its speed decreases n its always bends towords the normal. but if light will go perpendicularly form air to glass then it will not change its direction.
Is a CFL bulb natural source of light?
You do not found C.F.L. bulb in nature as such. So it is an artificial or man made source of light. It consumes very less energy. As it does not gives out heat.
Why is a shadow always on the opposite side of the light source?
Your shadow will fall in the direction opposite the source of light - with you between the light source and the shadow. The direction of your shadow relative to you will depend on what direction you are facing.If you are facing toward the light source, the shadow will be behind you.If you are facing away from the light source, it will be in front of you.If you have the light source to your right, the shadow will be to your left.If you have the light source to your left, the shadow will be to your right.If the light source is directly above you, the shadow will be directly under you.If you move past a light source, your shadow will move from behind you to beside you and then to in front of you.
What does the sun do to your shadow?
The shadow is the region where less light strikes.
What are the characteristics of a shadow?
Shape of object between light source and viewing shadow, less light, etc.

What are characteristic of shadow?

Does the light of the moon cause a physical shadow?
A shadow is caused when there is less light or no light in an area. An object can block the light and thereby cause a shadow. If the light reflecting off the moon is a source of light, objects blocking this light can cause a shadow.
What happen to the shadow if the light get dimmer?
If the light gets dimmer, the shadow will become less defined and appear lighter. As the light source decreases in intensity, the shadow cast by the object will become less sharp and more diffused.
Do you need more or less light for a darker shadow?
More light
What happen to the shadow as the light source gets farther?
The shadow will become less defined.
How is a shadow affacted by the brightness of the light source?
The brightness of the light source affects the darkness and sharpness of the shadow. A brighter light source produces a darker and more defined shadow, while a dimmer light source creates a lighter and less distinct shadow.
How is a shadow affected by the brightness of the light source?
The brightness of the light source determines the intensity of the shadow. A brighter light creates a sharper and more defined shadow, while a dimmer light results in a softer and less defined shadow. Additionally, the size of the light source can also affect the sharpness of the shadow edges.
Why is the shadow bigger if the light source is nearer?
When the light source is closer to the object, the light rays diverge less, resulting in a sharper shadow. This makes the shadow appear larger relative to the object because the edges are well-defined. On the other hand, when the light source is farther away, the light rays diverge more, creating a softer shadow with less defined edges.
