The beam would be deflected to the negative plate, as alpha particles are Helium nuclei and are positively charged.
The beam of alpha particles is deflected toward the negatively charged plate. This is because alpha particles are positively charged, and opposite charges attract each other.
Alpha particles can be blocked by a block of lead due to their relatively low penetrating power, while beta particles may require a thicker shield, such as a piece of aluminum or plastic, depending on their energy. Lead is not as effective at blocking beta particles as it is for alpha particles.
Cathode rays are deflected away from a negatively charged plate because they are negatively charged particles themselves. Like charges repel each other, so the negative cathode rays are pushed away from the negative plate.
The alpha particle is the nucleus of a helium atom and hence has 2 protons and 2 neutrons. The neutron is neutral and the proton has a +1 elementary charge. The alpha particle therefore has an elementary charge of +2
For photographic plates silver halides are used.
photographic plate
An alpha particle is made up of two protons and two neutrons, giving it a positive charge. As opposite charges attract, the positive charge of the alpha particle is attracted to the negative charge of the plate.
Gamma rays do not affect the photographic plate as they are highly penetrating and pass through without creating an image.
No, alpha plate is not silver plate. Alpha plate is a type of base metal plating that contains alpha brass, which typically consists of copper and zinc. Silver plate, on the other hand, is a thin layer of silver that is electroplated onto a base metal.
Output to a photographic plate.
Instantaneous results. The primary advantage of the photographic plate over CCDs is image quality--an 8x10 plate carries a lot more image information than a CCD can capture.
