1. ### Confused about the number of absorption lines

Got the difference, thanks!
2. ### What is the magnitude of acceleration?

Yes, thank you!
3. ### Confused about the number of absorption lines

So why in question 5 didn’t we include transitions from n=3 to n=2 and n=2 to n=1, and n=3 to n=1...
4. ### Confused about the number of absorption lines

So they are indeed three possible transitions.
5. ### What is the magnitude of acceleration?

Probably yes. That’s a different book though.
6. ### Confused about the number of absorption lines

Here they are.
7. ### Confused about the number of absorption lines

I forgot to post the problem,too.
8. ### What is the magnitude of acceleration?

Because in the answer key it is C, the same, so I had to check:rolleyes:
9. ### Confused about the number of absorption lines

1. Homework Statement If an atom in energy level 1, how many absorption spectral lines can an atom exhibit due to transition between 3 levels? How about 4 and 5 levels? And also in emission? 2. Homework Equations Concept 3. The Attempt at a Solution I am confused one book says it can...
10. ### What is the magnitude of acceleration?

1. Homework Statement Objects X and Y, shown below, are released fronm rest in outer space. The only force acting on the objects is their mutual gravitational attraction. The mass of X is one-half that of Y. With respect to the original rest frame, the magnitude of the acceleration of X is...
11. ### What are the frequency and speed of a photon after scattering

1. Homework Statement Photons incident upon free electrons that are essen- tially at rest are scattered by the electrons. As a consequence, the electrons gain kinetic energy. How do the frequency and speed of the photons present after the scattering compare to those present before the...
12. ### Which graph represents the Energy of a photon vs intensity?

I don’t know why the answer key says it is C, so I had to check on my understanding.
13. ### Which graph represents the Energy of a photon vs intensity?

1. Homework Statement If X represents the intensity of monochromatic blue light and Y represents the energy of each photon of the light, which one is the correct graph below? 2. Homework Equations KE=hƒ-∅, where ∅ is the work function Energy of a photon= hƒ 3. The Attempt at a Solution...
14. ### Elliptical orbit/ determine speed & potential energy

1. Homework Statement True statements about Jupiter as it moves in its elliptical orbit around the Sun include which o the following? I. It has its greatest speed when closest to the Sun. II. It has its greatest potential energy when farthest from the Sun. III. The magnitude of its...
15. ### Path length differences/ interference problem

1. Homework Statement In the figure below, Two wave sources, M and N, are vibrating in phase on the surface of water and generate waves of wavelength λ. Which of the following values for the distances MP and NP will result in minimum disturbance at a particular point P on the surface of the...
