When electromagnetic waves strike an obstacle, what usually happens is that part of the wave is absorbed by the obstacle, part is reflected back and part is transmitted through the material.
However, in case of a dark object; the dark object acts as a perfect absorber and absorbs all the electromagnetic waves.
So, the right answer is the diagram showing only absorption of the wave by the surface.
What two conditions are necessary for osmosis to take place
The conditions required for osmosis are:
Two solutions having different solute concentration.
A semi-permeable membrane. When two solutions having different concentration of solutes is separated by a semi-permeable membrane, the solvent moves from the region of high concentration of solvent
Answer:
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation. It's also weaker at higher altitudes, further from Earth's centre, such as at the summit of Mount Everest
