Which of the following radiation is passed through electric field?
These radioactive emissions are called beta rays. A part of the beam is deflected downward indicating that these particles are positively charged. These radioactive emissions are called alpha rays. Notice that the alpha particles are deflected less than the beta particles by the same electric field.
Which of the following radiations when passes through electric field gets attracted towards +ve plate?
Cathode rays are deflected towards positive plate in an electric field.
Which radiation is deflected the most in electric field?
Beta Particles in an electric field
This confirms that they are negatively charged. Beta particles are fast moving electrons with a very low mass and so have a high charge to mass density. They are deflected much more than the heavier alpha particles.
What happens when cathode rays pass through the electric field?
When the cathode rays are passed through an electric field between two parallel plates, cathode rays are deflected towards positive plate. This determines the charge of the particles constituting the cathode rays. As these are deflected towards positive plates, the particles of cathode rays are negatively charged.
What are the 3 types of radiation How do they behave in an electric field?
Alpha rays (heavy, positively charged particles) are deflected slightly in one direction. Beta rays (light, negatively charged electrons) are deflected strongly in the opposite direction. Electromagnetic gamma rays are not deflected.
Which rays are deflected in electric field?
Alpha particles are positively charged, beta particles are negatively charged, and gamma radiation is electrically neutral . This means that alpha and beta radiation can be deflected by electric fields , but gamma radiation cannot.
Are cathodes negative or positive?
During discharge the positive is a cathode, the negative is an anode.
Why cathode rays are green?
When they struck atoms in the glass wall, they excited their orbital electrons to higher energy levels. When the electrons returned to their original energy level, they released the energy as light, causing the glass to fluoresce, usually a greenish or bluish color.
Which radiation is not affected by electrostatic field?
Gamma ray is electromagnetic wave which is neutral. So gamma ray is not affected by electric and magnetic field.
Which is not deflected by electric field?
Alpha particles are positively charged as they have two protons and two neutrons. … This means that alpha and beta radiation can be deflected by electric fields, but gamma radiation cannot. Hence the types of waves that cannot be deflected by an electric field or a magnetic field are gamma rays.
