What else can I help you with?
Do smoke particles allow light to pass through?
No, smoke particles can block or scatter light as it passes through, leading to a decrease in overall light transmission. This effect can cause visibility issues and contribute to poor air quality in smokey environments.
How can you see path of light through smoke?
You can see the path of light through smoke because the particles in the smoke scatter the light. When light enters the smoke, it hits the particles and scatters in different directions, making the path of the light visible. This effect is commonly seen in settings like laser light shows or sunbeams filtering through smoke-filled rooms.
Is smoke a transparent medium?
No, smoke is not considered a transparent medium because it does not transmit rays of light through it. An example of a transparent medium would be glass.
Does infrared radiation penetrate through smoke?
Yes, long-wave infrared will penetrate even very dense smoke. That's why thermal imagers are effective in firefighting. For instance, you can feel the heat (infrared spectrum) through smoke, but you cannot usually see through smoke (visible spectrum).
Why does smoke from a bonfire rise upwards?
Some chemicals that constitute smoke are of lighther weight than others; thus, the lighter chemicals rise through the atmosphere faster than the heavier ones. This creates the swirling or curling effect.
Do smoke particles allow light to pass through?
No, smoke particles can block or scatter light as it passes through, leading to a decrease in overall light transmission. This effect can cause visibility issues and contribute to poor air quality in smokey environments.
How does Bosch smoke meter work?
The Bosch smoke meter operates by measuring the opacity of exhaust smoke emitted from diesel engines. It uses a light source to project a beam through the exhaust gas, and a photodetector captures the amount of light that passes through. The density of the smoke is determined based on the amount of light absorbed or scattered by the particulate matter in the exhaust. This measurement helps assess the engine's performance and compliance with emission standards.

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.
Why does smoke show tyndall effect?
The Tyndall effect occurs when light is scattered by particles in a colloid or very fine suspension. Smoke consists of tiny solid particles dispersed in air, which are large enough to scatter light but small enough to remain suspended. When a beam of light passes through smoke, these particles scatter the light, making the beam visible. This phenomenon highlights the presence of the small particles in the smoke.
Why does the airplane create smoke?
It's not smoke, it's steam. When the water in the air passes through the airplane's engines, it warms up and becomes steam.
Does smoke create rainbows?
Light passing through a transparent medium like glass/water does. Smoke is made of small particles of unburnt carbon, and light passing through is does not get split into a rainbow.
Is gun sound and smoke produced at the same time?
The smoke is produced slightly before the sound. Smoke is produced by the ignition of the propellant in the round. The sound is produced when the bullet passes through the sound barrier.
Is smoke a transparent medium?
No, smoke is not considered a transparent medium because it does not transmit rays of light through it. An example of a transparent medium would be glass.
What is opaque gas?
Opaque gas refers to a gas that does not allow light to pass through it, resulting in it appearing cloudy or dense. This can occur when the gas contains particles or impurities that scatter or absorb light. Some examples of opaque gases include smoke, smog, and certain industrial emissions.
Does infrared radiation penetrate through smoke?
Yes, long-wave infrared will penetrate even very dense smoke. That's why thermal imagers are effective in firefighting. For instance, you can feel the heat (infrared spectrum) through smoke, but you cannot usually see through smoke (visible spectrum).
Sentences with the word dense?
The smoke was so DENSE I couldn't see my 2 hand in front of me
