Send the three radiations through a magnetic field and they part company. One curves gently one way, another swings sharply the other way, and the third sails straight on, untouched.
Because alpha is positive and beta is negative, they are deflected in opposite directions by electric and magnetic fields. Gamma has no charge, so it is not deflected. Beta is deflected far more than alpha because it has a much smaller mass.
In electric and magnetic fields, alpha (positive) and beta (negative) are deflected in opposite directions, while gamma (no charge) is not deflected.
Gamma carries no charge, so a field cannot deflect it.
Pass each radiation through a field and watch which way, and how much, it bends.
Four quick checks. Each correct answer earns XP and lights this skill on your star map.
In a magnetic field, gamma radiation is...
Alpha and beta particles are deflected in...
Beta is deflected more than alpha because beta has...
Gamma is not deflected because it has...
The charge sets the direction; the mass sets how much it bends.
| Radiation | Behaviour in a field |
|---|---|
| Alpha (positive) | Deflected one way, only a little (heavy) |
| Beta (negative) | Deflected the opposite way, a lot (very light) |
| Gamma (no charge) | Not deflected at all |
Gamma is undeflected because it carries no charge. Alpha and beta deflect in opposite directions because their charges are opposite, and beta deflects far more than alpha because it is so much lighter.
Unlocks once the four checks above are done. Worth more XP, written in the style of Paper 2.
Three radiations enter a magnetic field. One is undeflected. It is...
Alpha and beta curve in opposite directions in a magnetic field because they...
In the same field, beta is deflected through a larger angle than alpha mainly because beta...
Deflection of radiation is mapped. Keep the chain going.
