What Property Of Light…..? What property of light allows shadows to form?
Light is normally radiated on a straight light. Gravity can affect light and actually bend the beam. It can also be reflected or re-directed by mechanical means.
The reason that shadows are formed is when a solid object blocks the light, preventing the beams from continuing. The “blocked” light is represented by a shadow.
What Is Light……………..? What makes light travel faster than any other thing?
does dimmer light travel slower than bright light? how come in far distance, we see bright light better than dim light?
Is laser light? Does laser travel at the same speed as light?
Light is a type of radiation, in the electromagnetic spectrum. You can get lots of types of light – radio waves are classed as light, along with x rays, so these travel at the same speed ? dim light travels at the same speed as bright light. Dim light just has less…energy (less photons are released, and photons are pockets of energy). Light will obviously lose intensity the further you are, because the photons spread out more. If dim light releases less photons, there is more chance that all of them will be lost by the time they reach your eye than bright light with lots of photons ?
A laser is light, so travels at the same speed
What Is Light? We know that sound is made of waves. Then, what about light?What is light? What is it made of?
Light is electromagnetic radiation of a wavelength that is visible to the eye (visible light).
Light is composed of an elementary particle called a photon.
Light can exhibit properties of both waves and particles
Light Cigarette’s Question? Whats the difference between Light Cigs and Non Light
Many smokers choose "low-tar," "mild," "light," or "ultra-light" cigarettes because they think that these cigarettes may be less harmful to their health than "regular" or "full-flavor" cigarettes. Although smoke from light cigarettes may feel smoother and lighter on the throat and chest, light cigarettes are not healthier than regular cigarettes. The truth is that light cigarettes do not reduce the health risks of smoking. The only way to reduce a smoker's risk, and the risk to others, is to stop smoking completely.
What about the lower tar and nicotine numbers on light and ultra-light cigarette packs and in ads for these products?
These numbers come from smoking machines, which "smoke" every brand of cigarettes exactly the same way.
These numbers do not really tell how much tar and nicotine a particular smoker may get because people do not smoke cigarettes the same way the machines do. And no two people smoke the same way.
How do light cigarettes trick the smoking machines?
Tobacco companies designed light cigarettes with tiny pinholes on the filters. These "filter vents" dilute cigarette smoke with air when light cigarettes are "puffed" on by smoking machines, causing the machines to measure artificially low tar and nicotine levels.
Many smokers do not know that their cigarette filters have vent holes. The filter vents are uncovered when cigarettes are smoked on smoking machines. However, filter vents are placed just millimeters from where smokers put their lips or fingers when smoking. As a result, many smokers block the vents--which actually turns the light cigarette into a regular cigarette.
Some cigarette makers increased the length of the paper wrap covering the outside of the cigarette filter, which decreases the number of puffs that occur during the machine test. Although tobacco under the wrap is still available to the smoker, this tobacco is not burned during the machine test. The result is that the machine measures less tar and nicotine levels than is available to the smoker.
Because smokers, unlike machines, crave nicotine, they may inhale more deeply; take larger, more rapid, or more frequent puffs; or smoke a few extra cigarettes each day to get enough nicotine to satisfy their craving. This is called "compensating," and it means that smokers end up inhaling more tar, nicotine, and other harmful chemicals than the machine-based numbers suggest.
What is the scientific evidence about the health effects of light cigarettes?
The Federal Government's National Cancer Institute (NCI) has concluded that light cigarettes provide no benefit to smokers' health.
According to the NCI monograph Risks Associated with Smoking Cigarettes with Low Machine-Measured Yields of Tar and Nicotine, people who switch to light cigarettes from regular cigarettes are likely to inhale the same amount of hazardous chemicals, and they remain at high risk for developing smoking-related cancers and other diseases.
Researchers also found that the strategies used by the tobacco industry to advertise and promote light cigarettes are intended to reassure smokers, to discourage them from quitting, and to lead consumers to perceive filtered and light cigarettes as safer alternatives to regular cigarettes.
Even Lighting Is Provided By? A) frontal lighting
B) oblique lighting
C) side lighting
D) edge lighting
???? ?????????? – I would not talk about others not knowing the answer when you yourself have given the wrong one. (unless of course you are deliberatly giving the wrong answer which I actually doubt considering some of your other questions/answers).
Look up what oblique lighting is – it is most certainly not even lighting.
The reason people give answers saying “do your own homework” is simply that by asking a multiple choice question and getting the answer on here means the individual is not learning anything.
It is very very simple to do a search on the terms and to read the definitions. You may actually learn what you are doing that way.
This question is very very very easy to figure out (except for ???? ?????????? though it would seem) if you actually think about it just a little bit.
Which Lighting Is More Accurate? The lighting on a photo or lighting on a mirror?
The lighting over mirror might be good enough for brushing your hair or applying makeup, but the lighting used to shoot portraits is very different. It usually includes at least one off camera light, but usually two, a key and fill light. Most photographers also use what is called a hair light and some kind of background lighting.
They are totally different. The light over your mirror will produce shadows under your eye sockets and nose.
