What are the three types of radiation that occur in the vacuum tube?
The three types of radiation that occur in a vacuum tube are X-rays, alpha particles, and beta particles. X-rays are produced when high-speed electrons strike a metal target, while alpha and beta particles are emitted during the decay of radioactive materials within the tube.
Why was a vacuum used for Rutherford's gold foil experiment?
A vacuum was used in Rutherford's gold foil experiment to reduce interference from air molecules that could scatter the alpha particles, leading to inaccurate results. The vacuum helped create a controlled environment for the experiment, allowing the alpha particles to pass through the gold foil without deflection by air particles.
Alpha particles ejected from the nucleus travel at the speed of light?
Alpha particles are emitted from the nucleus at high speeds, typically around 5-10% of the speed of light. They move with such energy due to the strong repulsive force between the positively charged alpha particle and the remaining nucleus.
Why did Geiger and Marsden's experiment take place in a vacuum?
Geiger and Marsden's experiment took place in a vacuum to minimize interactions between the alpha particles and air molecules. This allowed them to study the deflection pattern of alpha particles by the gold foil accurately, without interference from air molecules that could scatter the particles in unpredictable ways.
Why did Rutherford use a vacuum?
Rutherford used a vacuum in his experiment to eliminate any air molecules that could interfere with the path of the alpha particles. This allowed him to study how the alpha particles interacted with the gold foil and draw conclusions about the structure of the atom.

Does an alpha particle and beta particle has the same speed in a magnetic field?
Alpha particles with the same energy as beta particles have much less speed, magnetic field or no.

What is alpha ionizing?
Alpha particles are helium nuclei emitted with energies of several MeV and travelling at about 5% speed of light. As air molecules take only about 35eV to ionize, highly charged alpha particles are very strongly ionizing.
Why is speed of light greater in vacuum?
Since there are essentially no particles in a vacuum to get in the light rays way. Thus less disturbance.
What is alpha ionizing radation?
Alpha particles are helium nuclei emitted with energies of several MeV and travelling at about 5% speed of light. As air molecules take only about 35eV to ionize, highly charged alpha particles are very strongly ionizing.
Why do the particles move faster in a vacuum?
In a vacuum, there is no air resistance or friction to slow down the particles, allowing them to move faster without any impediments. This lack of resistance enables the particles to move freely and at their maximum speed.
What are massless particles traveling the speed of light?
Massless particles traveling at the speed of light include photons, the particles of light. They have no rest mass and always move at the speed of light in a vacuum according to the theory of special relativity.
In which medium is the speed of light a maximum?
The speed of light is a maximum in a vacuum. In other media, such as air or water, the speed of light is slower due to interactions with the medium's particles.
