When your eyes can detect images, light from a light source(s) is being reflected from the objects you see directly to your retina.
For example, you are in a closed room with one overhead light fixture. The light from the light bulb is being filtered and scattered to light up some surfaces in the room. Light travels in a straight line. The shadow below a desk is where there is no direct light (no direct path to the light source). However, light scattered off the wall or chair will still reach below the desk, where you can still see a faded image. When you can see an image, bright or faded, it means that some light has reflected off that surface to reach your eyes. A bright image is seen when more light reaches that surface and reflects to your eyes than a fuzzy image.
=========================
When light reflects, on an object it bounces off of the object and you can see the object much more clearly.
No, to see objects without the presence of light is impossible. Even a little light will help you see an object. Light has to reflect from the object to the eye to allow you to see it.
light rays are reflected off the object
Any object you can see reflects light. If it did not reflect any light it would be invisible. Similarly, no object is so reflective that it reflects all light. The proof that it absorbs light is that it increses in temperature as it is exposed to light.
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.
We need an source of light, an opaque object blocking the path of light, a screen behind the opaque object.
When the light falls on an object , then it can be visible to our eyes , because of light . This is called reflection on an object . Hence , the statement : We can see through a glass has a question that : How will we see through a glass ? So whenever the object is in the path of the light the object is visible to us .
To see a shadow, you need a source of light, an object to cast the shadow, and a surface for the shadow to be projected onto. When the light is blocked by the object, a shadow is created on the surface opposite the light source.
When we see an object, we see light that is reflected off of the object and into our eyes.
-- Light has to shine on the object, and some of it has to reflect off of the object. -- Some of the reflected light has to make it to the mirror. There can't be any physical obstruction in the path. -- The mirror has to be clean enough so that some of the light hitting the mirror is reflected away from it. -- Your eye has to be on the path taken by the light after it reflects from the mirror.
-- You "see" only when light enters your eye. -- You 'see' an object only when light from that object enters your eye. -- If the object itself doesn't generate light, then light from some other source must illuminate the object, and some of that light must reflect from the object to your eye. -- In absolute darkness, there is no light, and you do not 'see'.
No you see the object because the light refelects from the object into your eyes
if light from a light globe hits an object as a book it usually reflects on that object we can see them because of the light reflected on them
No.
You see the colors of light that are reflected off the object. The colors you see depend on the wavelengths of light that the object reflects. For example, if an object reflects green light and absorbs all other colors, you will perceive the object as green.
You can see a path of light in a sunbeam when there are particles in the air, like dust or pollen, that scatter the sunlight. This scattering causes the light to become visible and creates the beam that you can see.
Light. Since light is a refraction of energy from an object to another object, and does not weigh anything, it cannot take up space. You can walk through it, but you cannot feel it. You can almost always identify the source of the light, and once you do, you will see it is something creating that light from the chemical reaction within that object.
