What is a photographic print made by placing objects on light sensitive paper and exposing it to light?
A photogram
How were photograms invented?
A photogram is a photographic image made without a camera by placing objects directly onto the surface of a light-sensitive material such as photographic paper and then exposing it to light. In a darkroom, or a darkened room, objects are arranged on top a piece of photographic material, usually photographic paper. When the operator is satisfied with the arrangement, the photographic material is exposed with light, usually by switching on an enlarger or other artificial light source. The material is then processed, washed and dried. The usual result is a negative shadow image that shows variations in tone that depends upon the transparency of the objects used. Areas of the paper that have received no light appear white; those exposed through transparent or semi-transparent objects appear grey.
Why does a mirror and a leaf reflect light differently?
Light is reflected of metal when it is polished and flat because it is very light and lighter colors reflect light whereas darker colors such as green suck the colors in.
Different colors are the result of?
Every object in the universe has a unique way of absorbing energy. Therefore they reflect various rays of wavelengths. Hence, the different colours is the result of the light waves with different wavelengths.
If a glass prism were placed in a medium such as water would it separate light into different colors?
Yes it would because if the glass was clear the prism would reflect off of the light and go right through the glass.

What type of image is produced by a photogram?
A photogram is a photographic image made without a camera by placing objects directly onto the surface of a photo-sensitive material such as photographic paper and then exposing it to light.
How does one produce a photogram?
One can produce a photogram by making a print in a photo lab without using a camera. To do this, one places objects onto a piece of light, sensitive paper in a darkroom. Then, one can use an enlarger to cast light onto the paper to capture the silhouettes of the objects placed.
Do only shiny objects reflect light?
No, everything that we can see (besides objects the produce light eg sun, light bulb) reflect light. If it didn't reflect light we would not be able to see it.
Could dark objects reflect light?
Yes. There is hardly anything that reflects NO light; dark objects simply reflect less light than light objects.
Why do colours of objects look different in the night?
there is no light to reflect off the object that you want to see
Why do different objects appear to the naked human eye in different colors under white light or normal light condition?
Each material reflect different the light waves.
Why cant light pass through dark objects?
Dark objects do not reflect light. Light is absorbed by them.
What is it called when objects reflect light?
reflection
What is produced when objects reflect light?
grey
Why can't you see reflection in all objects that reflect light?
You cannot see your reflection in all objects that reflect light because of diffuse reflection.
Why cant you see your reflection in all objects that replect light?
You cannot see your reflection in all objects that reflect light because of diffuse reflection.
