Is shadow an example of matter?
No, a shadow is just what happens when light from the Sun or another light source is blocked when it hits you. Because there is less light where it would be if you didn't block it, the ground and whatever doesn't have as much light appears darker. These phenomenons do not take up any space. Hope this helps!
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.
When light travels from air into glass the wave speed?
Its speed would decrease upon moving from a less dense to a more dense medium
Do you need more or less light when viewing a stained preparation?
More light for stained. Less light for unstained. When viewing unstained material, it is necessary to reduce the amount of light to increase the contrast between the cells and the liquid.
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 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.
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.
Is speed of light faster than speed of shadow?
When we discuss moving faster than the speed of light, we are really talking... The speed of a shadow is therefor not restricted to be less than the speed...
Why do a shadow form behind the a tree?
We can only see something if light is reflected off it. Our eyes see shadows because there is less light reflected from the shadow than the surrounding area.
How is a shadow formed explain?
A shadow is made when an object blocks out light coming from a light source. because there is less light particles in that area, surfaces don't reflect as much, making it darker in that area. that is why you can't see when there is no light source.
