Is this question from a physics GCSE homework sheet? As I think i have the same sheet! This is the only question i have not found the answer to yet.
I think the sheet is P2.11 2a (well, that's what it is called at the top of the sheet).

Why is gamma radiation different from alpha and beta radiation?

Gamma radiation is a type of electromagnetic radiation, whereas alpha and beta radiation are composed of particles. Gamma rays have the shortest wavelength and highest energy, whereas alpha and beta particles are larger and less penetrating. Gamma radiation does not carry an electric charge, while alpha and beta particles do.


Why alpha particles loses energy?

Alpha particles lose energy primarily through interactions with the surrounding medium, such as collisions with atoms. These collisions can cause the alpha particles to slow down and eventually come to rest. Additionally, alpha particles may also lose energy through ionization and excitation of the atoms they pass through.


What is the shortest wavelength radiation in balmer series?

The shortest wavelength radiation in the Balmer series is the transition from the n=3 energy level to the n=2 energy level, which corresponds to the Balmer alpha line at 656.3 nm in the visible spectrum of hydrogen.


How does an alpha particle move through a magnetic field?

An alpha particle is positively charged and will experience a force perpendicular to its velocity when moving through a magnetic field. This force will cause the alpha particle to follow a curved path due to the Lorentz force. The direction of the curved path will depend on the charge of the alpha particle and the orientation of the magnetic field.


How far does an alpha particle travel?

This depends on their energy. An alpha particle that comes from nuclear decay is usually only able to travel a short distance, a few centimeters, through air. Alpha particles as cosmic rays, however, are much more energetic, and can penetrate quite deeply, even through many meters of solid shielding. These can penetrate the atmosphere.
