If the surface is completely reflective then the angle at which the incident light leaves the surface will be different. For a rough surface the light would be scattered, whereas for a smooth surface they would reflect at the same angle the hit. If the surface isn't completely reflective then the angle and speed and which the light enters the object. For a rough surface the angles will random and based on the refractive index of the material. For a smooth surface they will be proportional to the sin of the angle times the refractive index.

How mass affect surface area?
Mass has no direct effect on the surface area of an object. You can increase mass without changing anything other property of an object. Volume, Size, and Shape effect surface area.
How does surface area effect heat loss?
the larger the surface area you have, to more heat that you are going to lose.
Surface-area-to-volume ratio in nanoparticles?
Surface area to volume ratio in nanoparticles have a significant effect on the nanoparticles properties. Firstly, nanoparticles have a relative larger surface area when compared to the same volume of the material. For example, let us consider a sphere of radius r: The surface area of the sphere will be 4πr2 The volume of the sphere = 4/3(πr3) Therefore the surface area to the volume ratio will be 4πr2/{4/3(πr3)} = 3/r It means that the surface area to volume ration increases with the decrease in radius of the sphere and vice versa.
What is the effect of dividing a big particle into smaller ones on the total exposed surface area?
The total surface area increases.
When will be the effect of Volume and Surface Area of Spherewhen cut in to two half?
The volume will be halved and the surface area will be halved but with the base area of pi*radius2 added to it
What is an albedo effect?
The fraction of the total light incident on a reflecting surface, especially a celestial body, which is reflected back in all directions.
What effect does the earths magnetic field have on the intensity of cosmic rays striking the earths surface?
The earth's magnetosphere acts as a shield to deflect harmful energies away.
In the phenomenon known as the Doppler Effect electrons are ejected when light shines on certain substances?
The Doppler Effect is the change in the frequency of the sound you hear when a car sounding its horn passes you.When the electrons at the surface of an object absorb incident light sufficient for them to escape the surface this is known as the photoelectric effect.

How does running on grass effect a mans movement compared to running on a smooth surface?
running on grass affects a mans movement compared to running on a smooth surface because when he is running on grass, the grass and soil underneath the grass is soft and causes him to not run as fast as he could while on a flat, hard surface.
Experts anticipate that a incident is the least likely to occur but would have a great impact upon the environment and people?
A nuclear incident would have a great impact on the environment and people, but would be the least likely to occur.Several people answered "biological", but I would question the "least likely" aspect. A nuclear incident would have a greater effect on the environment compared to a biological incident.

How does the greenhouse effect work relative to earth's energy balance?
The balance of incident Solar radiation as compared to the Re-Radiation of the same incident Solar radiation is skewed so that the Re-Radiation is cancelled and the Heat - easily in infra-red form - is Retained at and by the Earth.
How does soil contamination effect deer?
by striking their torn mills or talalas
Effect of intensity?
The photoelectric current is directly proportional to intensity.It also depends upon frequency, but frequency more than "THRESHOLD FREQUENCY" does not effect the current.The no. of electrons emitted per second by a photo-sensitive surface is directly proportional to the intensity of the incident radiations.So,the photoelectric current depends upon the intensity of the incident radiations.
