What else can I help you with?
Can light be separated into colors?
Using a prism a beam of light can generally be defracted into the different colors that make up that beam of light. The visible spectrum of red, orange, yellow, green, blue, indigo, and violet can often be seen.
Is tyndall effect exhibited by the dust particles suspended in the movie projector's beam of light in a dark room?
The Tyndall effect, also called Tyndall scattering, is light scattering via particles in a fine suspension. This effect normally creates strange color tinges when only this scattered light is seen, whereas with the movie projector the only real effect of the dust is revealing the beam of light, as the light itself still hits the screen clearly.
Would a laser be visible in a vacuum?
It depends on how you mean it. If one is holding a laser and light is shining on it, then of course it can be seen. But I assume you are talking about a laser beam.For the spot where the beam hits some object, yes the illuminated spot is visible. A vacuum has no real effect on light. A vacuum environment is just an environment that has had all the air (and other material) sucked out of it (and thus all objects regardless of shape and size fall at the same speed, but one digresses) but this vacuum has little effect on light.On the other hand, if you're talking about seeing the beam itself then the answer is no. Light travels in a straight line unless it's path is effected by some matter. If a laser projects its light in any direction except directly at your eye, none of the light will enter your eye unless something causes its path to change. In air, there is usually some dust, smoke, mist, or some such stuff that scatters a small fraction of the laser light and allows you to see the beam. Even in perfectly clean air, the air itself scatters a very small fraction of the light, so a bright enough beam can be seen. But in a vacuum, there is no material to divert any of the light toward your eye, so you can not see it at all.
Is waxed paper and frosted glass are examples of materials that are transparent?
No. Frosted glass and wax paper are translucent. They pss light but cannot be seen through.
What is the base meaning of transparent?
Having the property of transmitting rays of light, so that bodies can be distinctly seen through; pervious to light; diaphanous; pellucid; as, transparent glass; a transparent diamond; -- opposed to opaque., Admitting the passage of light; open; porous; as, a transparent veil.
Can a beam of light be seen as it passes through a compound?
No, a beam of light passing through a compound is not visible unless there are particles or impurities present that scatter or reflect the light. In a pure compound, light passes through without any significant interaction, making it invisible to the naked eye.
Does the beam of light shows tyndall effect in jelly juice?
Yes, a beam of light passing through jelly juice can show the Tyndall effect. The particles in the jelly juice scatter the light, making the beam visible as it passes through the liquid. This effect is commonly seen in colloids like jelly juice.
What are electron microscopes capable of revealing details much smaller than those seen through light microscope?
Because the electron beam has a wavelength lower than visible light.
What is a Ray of light in the air?
A ray of light in the air is a thin beam of light traveling through the atmosphere. The ray can be produced by natural sources like the sun or artificial sources like light bulbs. It can be seen as a visible stream of photons passing through the air.
How can you use a light beam to identify a solution from a suspension?
Because of the different properties of solutions and suspensions, a beam of light can be used to differentiate the two. If a beam of light passes through the sample, it is a solution, not a suspension. Conversely, if a beam of light does not pass through a sample completely, it is a suspension, not a solution.
Why do lasers appear in smoke or water?
In order to be seen, light must reach the eye. Since laser light is coherent, it travels only along its line of propogation, so there is no light to be viewed from the side of the beam. However, when a laser beam passes through fog, it is reflected off of tiny particulate droplets of water in the fog (or smoke particles in smoke), so is diffused in all directions and can be observed. In order to be seen passing through water, there must be suspended particles in the water from which the light can be reflected. The beam should not be visible as it passes through perfectly pure water.
Is beam of light is visible or invisible as it passes through a solution?
It depends on the solution. If the solution is clear and transparent, the beam of light will be visible as it passes through. However, if the solution is opaque or colored, the beam of light may be invisible or difficult to see.
Can atoms be seen through an electron microscope?
Yes, atoms can be seen through an electron microscope. Electron microscopes use a beam of electrons rather than light to visualize samples at nanoscale resolutions, allowing for direct observation of individual atoms.
Why does the sky appear black to astronaut?
Our atmosphere scatters the sunlight. Since there's no atmosphere in space light isn't defused. Think of a flashlight beam outside on clear dark night compared to the same beam seen through fog.
If the beam in a Teltron Tube is blue what is it that makes the electrons visible?
There is no gas in the bulb, only vacuum. The blue beam we see is a special flourid mix that sends out the blue stripe when the electron touches the paper and exidates the electrons in it.
What is a ray of sunlight?
A ray of sunlight is defined as 'a narrow beam of light' and is used to describe a small line or individualÊstream of sunlight.ÊA ray of sunlight is usually seen as multiple rays of sunlight not just one.Ê
How can one see an infrared light beam?
To see an infrared light beam, one can use an infrared camera or infrared goggles that can detect and display the infrared light as visible light. These devices convert the infrared light into a visible image that can be seen by the human eye.
