    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...

    Confused about the number of absorption lines

    So they are indeed three possible transitions.

    What is the magnitude of acceleration?

    Probably yes. That’s a different book though.

    What is the magnitude of acceleration?

    Because in the answer key it is C, the same, so I had to check:rolleyes:

    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...

    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...

    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...

    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.

    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...
