It was later found that n 2 and n 1 were related to the principal quantum number or energy quantum number. Jun 15, 2020 · The y-intercept is the point where the line intersects with the y-axis. Since the y-axis is located at x = 0, the x coordinate of the y-intercept is always 0. Example 1 (cont.): The y-intercept is at y = -2, so the coordinate point is (0, -2). Slope–intercept form. A non-vertical line can be defined by its slope m, and its y-intercept y 0 (the y coordinate of its intersection with the y-axis). In this case its linear equation can be written = +. If, moreover, the line is not horizontal, it can be defined by its slope and its x-intercept x 0. In this case, its equation can be written The Rydberg constant for Li+2 is 2.18x10-18 J. Part a: What is the longest wavelength seen in the visible absorption spectrum of Li+2 at ordinary temperatures? Part b.
