Yes, now we can - there are windows that have channels in them that divert fifty percent of their incident light towards photovoltaic materials in the window frame.
As well there are a dozen other means of Solar Photon capture.
A photograph is an image created by light falling on a light-sensitive surface
Because something opaque comes between the light source and the surface onto which the light is falling.
Reflection is bouncing back of light after falling on a polished surface while refraction is bending of light when it falls on a surface
The trick behind this is that light is photons, which are massless.
you use a special powder and a brush an brush it light ly an a flat surface
Cameras and light
What causes a shadow, to begin with. Yep, a shadow is the blocking of light falling onto a surface. If you don't have light shining on a surface to begin with, say, at night, you cannot have a shadow.
Shadows are caused when an object blocks part of a beam of light that is falling on a surface. The surface areas receiving less light are darker (less illuminated by the light) and may assume the same general shape of the object causing the shadow.
It is a ray of light which arrives at a point of reference. The latter may be a point on a mirror, a prism, lens, your eyeball or whatever.
Light falling on such surface gets scattered and hence no sharp image becomes possible.
Neglecting air resistance, a body falling freely near the earth's surface falls with an acceleration of 9.8 meters (32.2 feet) per second per second, regardless of how big, small, light, or heavy it is.
yes, the desert plant have long roots to collect water. Some desert plants have shallow roots that form a dense web just below the surface of the soil to collect water even from light rainfalls.
