What will be the effect of incident ray of light striking a rough surface compared to the same rays striking a smooth surface?
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 does surface area effect heat loss?
the larger the surface area you have, to more heat that you are going to lose.
What is the effect of dividing a big particle into smaller ones on the total exposed surface area?
The total surface area increases.
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 surface area on absorption of heat?
The surface area significantly affects the absorption of heat, as larger surface areas allow for greater interaction with heat sources, enhancing heat absorption. When a material has a larger surface area, it can absorb more heat energy compared to a smaller surface area, leading to faster heating. This principle is often observed in processes like cooking or heating, where a larger pan or container heats food more efficiently due to increased contact with the heat source. Thus, maximizing surface area can facilitate more effective heat transfer and absorption.
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
Which matters in the formation of photoelectrons?
The formation of photoelectrons is primarily influenced by the intensity of incident light and the energy of the photons striking the material. The material's work function, which is the minimum energy required to remove an electron from its surface, also plays a crucial role in determining the photoelectric effect.
What happens to electrons in the photo electric effect?
Electrons are ejected from a metal surface when it is exposed to light of sufficient energy. This phenomenon is known as the photoelectric effect. The energy of the incident light is absorbed by the electrons, causing them to be emitted from the metal surface.
When light is incident on a metal surface it emits electrons What happens if the intensity of light increases?
If the intensity of light increases, more photons will be incident on the metal surface, leading to a higher rate of electron emission through the photoelectric effect. This results in a higher current of emitted electrons.
In the phenomenon known as the Doppler Effect electrons are ejected when light shines on the 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.

What does light produce in a photoelectric effect?
In the photoelectric effect, light produces electrons when it strikes a material surface. The energy of the incident light is transferred to the electrons, causing them to be ejected from the material.
What incident do experts anticipate 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.

What is the most striking feature of Venus?
The most striking feature of Venus is its thick atmosphere composed mainly of carbon dioxide and clouds of sulfuric acid. These atmospheric conditions create a strong greenhouse effect, leading to surface temperatures hot enough to melt lead.
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 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.
