when a light ray is thrown on a PLANE surface
two things occur which cause light to reflect
1- the incident ray is equal to the reflected ray
1- the incident ray , the reflected ray and the normal, at the point of incidence, all lie at the same plane
Deflection occurs when light is reflected in one direction from a smooth surface. This happens when light particles bounce off of different surfaces.
At angles.
Absorbed
When light encounters a material, portions of it will be absorbed, reflected, and transmitted. Light that is not absorbed or reflected is transmitted, meaning we can see through the material. How much light is absorbed by a material has mostly to do with features on the molecular, atomic, or sub-atomic scale (e.g. whether electron orbitals can accept energy within a certain range). How much light is reflected (or scattered) has to do with the structural arrangement of the material (e.g. roughness). Transparent materials also absorb and reflect some light which is why you can see your reflection in a window if it is dark behind it.Sources:http://en.wikipedia.org/wiki/Transparency_and_translucencyWhy_does_light_reflect_in_a_mirror
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.
Electromagnetic radiation passes through materials it does not interact strongly with and which do not present many interfaces where there is a transition between materials of different density.
The rate of dissolution of a solid is dependent on the surface area reaction. By crushing the cube, the surface area is greatly increased, thus increasing the rate of dissolution.
A solution is formed as individual molecules from the solid are surrounded by molecules of solvent and then diffusing away from the surface of the solid being dissolved.
reflected.
plash
Physics defines capillarity as the action of a liquid being distorted by a solid hitting its surface. Examples of this include the ripples made by a stone hitting the surface of a lake.
If you can see the light reflected, then it has hit your eyes, and your brain is processing it as the sense of sight, if you cannot see it, then it has reflected somewhere other than your eyes-IE; back into space, or it is a wavelength of light that the human eye cannot detect.

The same with when a light hits a solid; the energy either gets reflected or absorbed. If light hits a dark colored solid, most of the light will be absorbed, and the black object will get warm.If light hits a light-colored solid, most of the light will be reflected, and the white object will stay cool.By the way, the same thing happens to both heat and light, because heat is a form of light; heat is also called infrared light.Further answerIt does depend somewhat on what form this heat is in. If it's radiation then the answer above is fine. But if it's in the form of say, hot air, then there won't be any reflection, just conduction of the heat from the air to the solid.

A solid object hitting the ground with the force of a meteor would leave a crater, a depression in the ground with a raised edge at the surface, similar to Meteor Crater in Arizona.
yes, it is, and i am a biology/science teacher and it is true that sound energy is reflected through a solid
When light ray strikes a black object (it does not matter if it is cloth or solid) some of the light is 'absorbed' and some of it is reflected back to the normal of the surface (pependicular). Reflected light continues its path and absorbed light is transormed usually into heat. For example if you leave black and white objects in the desert they will heat but the black one will reach higher temperature. In physics there is an idealistic object called 'perfect black body' and the light which hits it is not reflected but absorbed. This means ALL of the incoming light is transformed into heat and the scientist use this imaginary object to calculate the emission of this body. This is called 'heat emission of a perfect black body'.
Some of it is absorbed, some is reflected, and some passes through. How much of each effect happens depends on the wavelength of the light and the composition of the object.
Sound energy that pass through a solid is said to be reflected because as sound waves pass from air to a solid, some of the energy is reflected back into the air. Some of the energy will be absorbed by the new medium.
