Why must a Geiger Muller tube for detecting alpha particles have very high thin end window?
A GM (Geiger-Muller) tube for detecting alpha particles must have a very thin window because alpha particles are highly interactive, and they can be stopped with very little, such as only a few inches of air, a sheet of paper, your skin, etc. Typical GM detectors for alpha application use mylar as the window. Even so, the mylar does interfere with the alpha detection, but this is better than nothing.

What is newton's corpuscular theory of light?
Newton did not believe that light acted like waves, but like small particles which he called corpuscles ( not like blood cells). An example ... shoot a shotgun toward an open window with a large piece of carbboard outside. Shoot many times to get many 'particles' to hit the cardboard. There should be a discernable figure of the window. Now shine light thru the window and the same pattern shows up on the cardboard. He thought that this proved that light was mado of millions and millions of small particles,
Can you detect radon gas with a geiger counter?
No, a Geiger counter cannot detect radon gas directly. Radon gas is a noble gas and does not emit the type of radiation that a Geiger counter is designed to detect. To measure radon gas levels, specialized devices called radon detectors or radon monitors are used. These devices work by monitoring the radioactive decay products of radon gas in the air.
To cause liquid water that has condensed on a window to evaporate what could you do?
You can increase ventilation by opening a window or running a fan to improve air circulation, which can help the water evaporate faster. You can also wipe the condensation with a cloth to remove the water from the surface. Finally, you can use a dehumidifier to reduce the humidity levels in the room, which will help prevent condensation in the future.
What is the area above and below a window called?
The area above a window is called the header or window lintel, while the area below a window is typically referred to as the windowsill or window ledge.
What are window valance ideas?
Window valences are decorative presentations of a home window. Generally, they are designed with a couch in the middle and the window spans over in a decorative and inviting presentation.
When radiation travels through the window of the geiger muller tube what happens so that the tube sends a signal that it has detected a particle?
When radiation enters the Geiger-Muller tube, it ionizes the gas inside. This ionization creates a conductive path that allows current to flow in the tube, triggering a voltage pulse that is counted as a particle detection event.
How do you use the geiger muller tube to test for alpha?
Do you want to verify that a radioactive source emits ONLY alpha particles? If so, first measure the original count-rate, with no radioactive source, on the GM-tube. This is the background count-rate. Next, place the radioactive source near the GM-tube, and measure the new count-rate. Place a thin piece of paper between the GM-tube and the source. You will see that the count-rate dropped to the background count-rate. This is because all of the alpha particles are absorbed by the paper. If there were other types of radiation, like beta and gamma radiation, the count-rate wouldn't drop to the background count-rate.
How do you move the geiger conter on lunar colany on poptropica?
You have to go to the most top middle window that was blocked by structures. Now, push the most left structure, and it will be the way for Geiger counter to get down to your Poptropica Lunar Colony Rover. Finally, you succeed to load Geiger Counters to the Rover.

Would an electromagnetic field have any effect on the reading of a Geiger-Muller tube and would I get false positives or negatives if I used it to detect beta particles in an electromagnetic field?
Yes, you could. The Geiger-Müller tube itself is fairly immune to electromagnetic fields by virtue of its construction. It's built inside a metal cylinder, which will offer some shielding. But outside the tube, things are different. Electromagnetic fields will deflect any charged particle (like a beta particle) that attempts to move through them. The amount and direction of the deflection of charged particles that move through a magnetic field will vary as a function of the direction of the magnetic lines of force relative to the path of the particle, the strength of the magnetic field, and the polarity and strength of the charge on the particle. Beta particles are high energy electrons, or sometime positrons, and the two particles will be affected oppositely by force on them created by their relative motion through the magnetic field. The term relative motion is important because it means the particle is moving in some way "across" or "through" the magnetic lines of force, and not "along" or "parallel" with them. Our beta particles, as they are generated and begin to move toward the GM tube, will encounter "diversion force" which will deflect them away from the original path of travel. This will affect their ability to actually get into the detector (the GM tube) through the window in it. And that will affect the count. It is improbable that looking for beta (or any charged) particles in a modest magnetic field will permit an accurate reading, and the reading will be "too low" because a number of the particles will be deflected away from the window of the GM tube. There is one more thing, and that's that it's hard for particles moving in an arc (along a curved course) to "hit a window" like the one in the GM tube and go in very far. Even if they get in the window, they will "curve across" the inside of the tube very near the window, and this might not allow them to trigger a current avalanche to record a "click" or a "count" for that particle. Readings could easily be very low if the detector is being used in a fairly stiff magnetic field. A link can be found below.
Which tiny particles are seen in a ray of light which falls from a gap of window?
Those particles are dust. Dust in a household environment is (are you prepared to be grossed out?) mainly flakes of dead skin.
Why should gamma rays be detected at a point within the Geiger-Muller tube rather that at the end of it?
Let's look at the construction of the tube. The Geiger-Müller (GM) tube is essentially a cylinder with a "wire" down the middle for an anode, and the inside of the cylindrical housing as the cathode. It's got some gas in it, and the type of gas will vary a bit from tube to tube and what is desired in the design. The "end" has a "window" in it made of thin glass or possibly mica. This window "lets in" the radiation while sealing the tube and providing a minimum amount of shielding that might "block" radiation, particularly alpha and beta radiation. Recall that alpha particles are helium-4 nuclei, and they can't penetrate a sheet of paper. Beta particles are high energy electrons, or possibly positrons, which can be stopped by a sheet of aluminum foil. You can't detect them if you block them. The way it works is as the radiation passes through the GM tube, it leaves an ionized "trail" in the gas behind it. This is primary ionization. The high voltage across the gas causes the ions to be accelerated toward the appropriately charged element. Positive charges move toward the cathode, and negative charges (electrons) move toward the anode. The movement of these charges ionizes other gas atoms, called secondary ionization, and the total effect is to create a current avalanche. With the movement of these charges and the accompanying current "spike" or "jolt" set off by the high voltage, we'll observe a "pulse" that the supporting circuitry in the detector can "see" and a "hit" or "count" is recorded by the Geiger counter. Gamma rays are penetrating types of (electromagnetic) radiation. They blast through the window and they ionize the heck out of the gas inside. It is basically the cumulative effect of all this ionization that creates sufficient ions to initiate the current avalanche that cause the counter to "pulse" electrically. The gamma rays have a field day zapping their way through the cylinder and creating lots ions to create a "click" or a count. In contrast, alpha and beta particles will not penetrate very far into the tube because of their limited ability to do so. This means that the current avalanche is more confined to the "front" of the tube. The superior penetrating power of the gamma rays means that their current avalanche includes a lot of volume deeper in the tube, or more "in the middle" than at the end of the tube, like the particulate radiation.

What is corpuscular theory of light?

An example ... shoot a shotgun toward an open window with a large piece of carbboard outside. Shoot many times to get many 'particles' to hit the cardboard. There should be a discernable figure of the window. Now shine light thru the window and the same pattern shows up on the cardboard.

Why is a window frame made of plastic not wood?
When solids are heated, they start to expand. This is because the particles inside vibrate more, the hotter they are.
