You were literally the only person I've come across that actually taught me about radiation deflection in a magnetic field, which was the one thing I didn't really understand. Thank you so much!

I've struggled with understanding why alpha particels deflected to the top and beta to the bottom, but thanks to you I completely understand! Massive thank you!

@satyakiray6856 4 жыл бұрын

Couldn't understand the application of Fleming rule in magnetic field

@lovattphysics6366 4 жыл бұрын

SmoidRay the rule is just about which direction your fingers are pointing. First finger points in the direction of the field, second in the direction of movement of positive charge (the opposite direction to a moving beta particle) and the thumb gives you the resultant force. Hope that helps!

this video is up to the mark. honsetly. but I got confused on the deflection of alpha and beta in the electric field as my book (Cambridge olevel by Heather...) represents alpha deflecting more than beta in the electric field which is totally against your provided lesson. can you help me out with some valid resources?i really depend on your quick response as your answer means a lot to me, my exams are at the top of my head. kindly answer me as soon as possible and thank you for such content .it really helped me a lot.

@ajsenju9383 4 ай бұрын

particles are accelerated due to weak nuclear force,so electrically charged forces of the electrodes oppose that vector, alpha is a general forceful emission but beta on the other hand a decomposition of neutron,similar velocity but alpha has much mote force(Newton's laws), so it would take more work,ie,more distance to express its force(w=fscosQ),and hence less deflection of a particle

Isn't gamma a photon which is a particle and has mass?

@lovattphysics6366 6 жыл бұрын

De Villiers du Plessis - yes, the gamma ray is a photon, which can be thought of as a particle. However, it has no mass and moves at the speed of light so it is very different to the alpha and beta particles. The most important thing that it does in this situation is transfer energy. That’s why it is easier to think of it purely as a wave (until you study Alevel or IB!)

@jiaee7839 5 жыл бұрын

Can I know why the second finger is pointing to the west but not to the south east or north

@lovattphysics6366 5 жыл бұрын

Jia Ee I think you’re talking about the magnetic field bit around 4:30? In which case this is Flemings left hand rule, which tells us the force on a conductor in a magnetic field. You have to always use your hand in the same position, and the first finger has to point in the direction of the field and the second finger has to point in the direction of movement of positive charge. In the case of the electron (which is negatively charged) the ‘movement of positive charge’ must be in the opposite direction to the movement of the electron, because if negative charge is moving to the right, then the left side is getting less negative = more positive, so positive charge can be said to move left. Hope that helps!

@lovattphysics6366 5 жыл бұрын

Jia Ee I think you replied again but I cant see it on here for some reason. The second finger has to point in the direction of movement of positive charge. The electron is moving right. So the movement of negative charge is to the right. Negative and positive are opposites so the movement of positive charge must be the opposite way to the movement of negative charge. So if the negative charge is moving right, the finger must point left. Hope that is more clear!

Can UV radiation be counted as background radiation

@lovattphysics6366 3 жыл бұрын

yiyiy7 opopopop nope. This kind of radiation (alpha, beta, gamma) is nuclear radiation, in that it comes from the nucleus of an atom. UV is not nuclear radiation so it doesn’t count here. Hope that helps!
