What levels result from a 4F term

AI Thread Summary
The discussion revolves around determining the energy levels resulting from a 4F term in atomic physics. The user correctly identifies that the "F" indicates L = 3, leading to seven possible magnetic quantum numbers (ml = -3 to 3). However, clarification is sought on the significance of the "4" in 4F, which typically denotes the multiplicity of the term. The conversation emphasizes the importance of understanding both the total angular momentum and the multiplicity in calculating the states associated with the term. Overall, the user is looking for guidance on the correct approach to solving the problem related to the 4F term levels.

Hi everyone!

I can't solve a problem. It is about the following task. How exactly should I proceed here?

Task A): What levels result from a 4F term? How many states are there at each level?

I tried many ways but none of them helped me to solve this problem.
However, I have some basic ideas: We have a F term, this means l=3, ml= -3,-2,-1,0,1,2,3. In sum we have 7 levels.
Is this reasoning correct or am I on the wrong track? I would welcome your response, thanks in advance.

(And I would like to apologize for my English skills because I come from a non-English speaking country.)

I assume you are using spectroscopic notation. You have correctly indicated that the "F" signifies L = 3.
What does the "4" in 4F signify?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...

Thread 'Correct statement about a reservoir with an outlet pipe'

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
