How can gamma rays be deflected?
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. Just as with electric fields, gamma radiation is not deflected by magnetic fields.
What would happen in a gamma ray burst?
With the gamma-rays beamed directly at Earth, the radiation would destroy a significant portion of our atmosphere, specifically the ozone layer. The photons streaming from the burst would cause chemical reactions leading to photochemical smog. This would further deplete our protection from cosmic rays.
Are gamma-ray bursts directional?
Recent observations have shown that the photons emitted from gamma-ray bursts all oscillate in the same direction, but for some reason, the direction changes over time. So far, gamma-ray bursts have only been detected in distant galaxies. However, it is possible for one to occur in our Milky Way galaxy.
Why are γ rays not deflected by electric and magnetic fields?
Gamma rays are high energy electromagnetic waves which do not have a net electrical charge. 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.
Which out of the three alpha beta and gamma rays are deflected in an electric and magnetic field give reason for your answer?
α and β are positive and negative charged particles respectively, therefore these are deflected in electric or magnetic field whereas γ radiations are not charged particles so does not deflect.
Would a gamma ray burst destroy Earth?
The scientists calculated that gamma-ray radiation from a relatively nearby star explosion, hitting the Earth for only ten seconds, could deplete up to half of the atmosphere’s protective ozone layer. Recovery could take at least five years.
