Why is the shadow formed by piece of grease paper different from the shadow formed by cardboard?
Grease paper is translucent. It let's a bit of light through but not all. Card board is opaque. It lets no light through. Therefore, the shadow cast by cardboard will be darker and more defined whereas the grease paper lets light through, making the shadow lighter and less focused.
What effects the size and tone of shadows formed?
The angle between the light source and the object that light's being shone at, the distance between the light source and object, the amount of light in the environment and the diffraction of the lights, and where the less or more phases of light reach, which cause the shadow to be darker or greyer.
How do you emphasize your green eyes?
-brown eye liner/eye shadow -purple liner/ shadow -a light/darker/more intense green (then your eye color) shadow/liner Mascara is a MUST!
Why tube light not shadow?
The reson behibd this is that when we stand in front of tube light because the length of tube light is much more than your width The light from the tube light are not paralel to each other. So they have a wide range. When you stand in front of a tube light we don not allow the rays to travel through us. But as I already mentioned that the rays are not parralel. As they are not parallel some of these ray cover the shadow which would have formed otherwise. But still there is a very dull shadow but we are not able to see it. But as you go away from the tube the shadowy portion starts to become darker and darker. Because the rays which would cover the shadow becomes less.
Do Lighter color surfaces reflect more or less energy than darker colored ones?
Light is energy. More light is reflected by light coloured surfaces. Therefore...
Why does the darker color of paper attract more heat?
It doesn't. Darker shade reflect less light, and the energy from any light that isn't reflected goes into heating up the object, but it's not "attracting" heat.
What materials form light shadows?
Any material that is not 100% transparent will produce a shadow in light. Even glass will produce some amount of a shadow.The more opaque a material is, the darker the shadow.The more transparent a material is, the lighter the shadow.
What property of light allows eclipse to be formed?
Light travels in straight lines. When the light hits the object it is stopped but the light at the edges continues to travel in a straight line so there is a shadow.The shadow is not black because another property of light. It can be reflected . When it hits an object some light is reflected. If the object is not perfectly smooth the light is scattered when it reflects.Light is reflected more from light colored objects than darker objects. So in a well lit area where there are plenty of surfaces the shadow will be less dark.A further property of light is that it will slightly bend around the corners of sharp objects. So if you look carefully you will see that the edges of a shadow are sometimes blurred. Usually this property is observed in the physics lab.Blurred edges of a shadow are more likely to occur from multiple light sources making a superimposed shadow.
How is a shadow related to absorption?
A shadow is what we call the absence of light due to some object coming in between the light source and surface on which the "shadow" falls. The 'object' which was in the way of the light could be, for example, solid rock or colored glass. Both block the direct path of the light, but at different rates and in different ways. The rock, would absorb a great proportion of the light due to its high density. The glass however, is less dense, therefore light passes through it more freely, with less of it being absorbed. Therefore more of it continuing to finally reach the surface. So to a certain degree, shadows are directly related to the physical makeup of the shadow casting object. The more the object absorbs, the darker the shadow will be and vice versa. There are phenomena I've chosen to leave out of my answer for simplicity. But you could start looking into volume properties and terms such as scattering, emission, extinction, optical density in addition to absorption.
Why a shadow forms behind a tree?
Light from the sun (or any other source) travels in particles, which strike objects and are often partially absorbed. A shadow forms behind a tree because when the particles hit the tree, they are absorbed and reflected, so that everything on the other side of the tree, where the light would have gone, receives no light. However, some light will bounce off of other objects and go behind the tree in the other particles' place. Since this other light will already have been partially absorbed, it will be more dim than direct light. Because of this, we are able to see in the shadow, but since the light there is not as strong, it is darker. This darker region behind the tree, is the shadow.
Light colored igneous rocks are less what than dark igneous rocks?
basaltic rocks are darker because they are more dence granitic rocks are less dence so they are lighter
When water is transparent then how is its shadow formed?
Because even though water is transparent, it diffracts (bends) light. When the water gets in the path of the light, some light will be reflected away at the surface, and more light will be diverted away by the diffraction. This will cause a loss of light energy on the other side of the water. Since the light in this area has less energy, it appears less bright, and this causes the "shadow".
