How is the shape and size of shadow affected if coloured is used instead of white light?
The shape of a colored shadow remains the same as a white shadow because it is determined by the object casting the shadow. However, the color of the shadow is influenced by the color of the light source. For example, a red light will cast a red shadow, giving the illusion of a different color shadow. Size of the shadow is not directly affected.

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 does a shadow form behind the dog when a light shines on it?
A shadow forms behind the dog when a light shines on it because the light cannot pass through the dog. Instead, the light is blocked by the dog, creating a region of darkness behind it where the light cannot reach. This creates the shadow that we see.
What affects the size and the shape of an objects shadow?
The size and shape of an object's shadow are affected by the angle of the light source, the distance between the object and the surface where the shadow is cast, and the shape and orientation of the object itself. The closer the object is to the light source or the surface, the larger and more defined the shadow will be. Additionally, the shape and texture of the object can also influence the appearance of its shadow.
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.

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 things might affect the size and position of a shadow?
The size of a shadow is affected by the angle and intensity of the light source, the distance between the object and the light source, and the size and shape of the object. The position of a shadow is influenced by the relative positions of the light source, the object, and the surface on which the shadow falls.
Woman with light-coloured hair?
light coloured
What affects was the size of a shadow?
The size of a shadow depends on, the angle that the light source is hitting the object and the size of the object. In some cases, the amount of light can also affect the size of a shadow.

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.
Why does a tree in the path of sunlight create a shadow instead of the light spreading around the tree?
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 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.
