Why does a tree in the path of sunlight create a shadow instead instead of the light spreading around the tree?
The (strong) tendency of light to travel in a straight line.
How does light pass through coloured jelly?
its the same as how light passed though glass and water. if you place a light behind the jelly there is a coloured shadow if front fo it because of how the light fragments as it passes though the jelly. the reflecion of the crystals in the jelly case the colour to show. same as how you can see what colour the jelly is in the first place
Did light have shadow?
light did not had shadow and will not have shadow.
Why is shadow black?
A shadow is caused by an object blocking light so that it doesn't reach a surface. The area in shadow appears black because there is no light falling on it -- it appears dark. In fact, most shadows aren't totally black, because light usually bounces around the obstruction off other objects (indirect lighting). You can also get coloured shadows where there are multiple light sources of different colours. e.g. in a nightclub or disco. Translucent objects may cast coloured shadows, e.g. stained glass in a church, where only some of the light has been blocked by the window. Outside on a sunny day, shadows may appear black because your eyes have compensated for the bright light and can't make out the detail. But if you walk into the shadow your eyes will adjust to the light, and you'll see that the shadow isn't black at all, it's just darker than in the direct sunlight. On a bright day with a blue sky, you may also see that areas in shadow (especially white objects in shadow) appear to have a blue tint. This is because although the shadow is not directly lit by the sun, it is lit indirectly by the blue sky above. It may not be very obvious, because your eyes and brain are adept at adjusting to changes in brightness and colour, but a camera will see it clearly. If you take a picture in shadow on a sunny day it comes out looking quite cold and blue. This is why many cameras have a 'shade' mode that alters the colours to remove the blue colour cast. To make your own coloured shadows, try experimenting with two or more torches with different coloured plastic over the bulbs. Place objects on a piece of white A4 paper (in a dark room), and move the torches around and note the effects.

Can a reflection be a shadow?
It is actually impossible to reflect a shadow, as a shadow is merely an absence of light. However, what IS reflected is the light surrounding the shadow. When this light is reflected, it forms a reflected image of the light's shape, complete with a lack of light, or shadow. In this way, it can look like a shadow is reflected.
Do coloured lights form coloured shadows Describe how you would find out for yourself?
No, it will not because coloured object still blocks the light from the light source. To find out how, place a piece of red block and place it in front of a torch in a dark room. The shadow would remain black
How is the shape and size of shadow affected if colored light is used?
No change will occur because shadow is a dark outline of an object, irrespective of the colour of the object or the colour of the light.

What is the physics behind a colored shadow?
A shadow is an absence of light from a point-source because it has been blocked by an object. The object's shape is projected on to the ground, wall or other surface. There might be light from another source illuminating the part that is shadowed, and that might be coloured.
Did light have shadow?
light did not had shadow and will not have shadow.
Why does a tree in the path of sunlight create a shadow instead of the light spreading around trees?
Light travels in straight lines and therefore some will hit the tree. Where this happens a shadow (absence of light) is created behind the tree.

What is dark colored and light colored?
Black is dark coloured and white is light coloured
What coloured light makes white light when mixed with green light?
Magenta coloured light makes white light when mixed with green light
Why coloured light produce colour by addition and pigment produce by subtraction?
Lights are coloured by the light they emit and are additive, while pigments are coloured by the light they absorb/reflect and are subtractive.
