- a. Calculate the energy of the following signal : g(t) = 10te -10r 0stsoIn the process of performing an analysis, you determine that you need to improve the precision by limiting the error in the absorbance to 9.400 x 10%. You attempt to achieve this by reducing the amount of stray light that reaches the detector. What is the maximum amount of stray light that can reach the detector that will limit the error in the absorbance to 9.400 x 10 for a true absorbance of 1.0000000? s= 222 x10-5 IncorrectThe characteristic K, and K, lines for titanium have wavelengths of 0.275 nm and 0.251 nm, respectively.

- The figure below depicts spectral reflectance measurements for three different materials: a green leaf from a healthy plant, a sheet of shiny blue paper, and the palm of a human hand. The measurements are labeled 1 (black line), 2 (red line), and 3 (blue line). Match the measurements to the most appropriate material typeThe Balmer series, or Balmer lines in atomic physics, is one of a set of six named series describing the spectral line emissions of the hydrogen atom. The Balmer series is due to transitions of electrons to the energy level with n=2. Using the ideas and treatment seen in class, find the three largest wavelengths corresponding to lines of the Balmer series. Express your results in nm.Problem 19: Sodium vapor light (average wavelength 598 nm) falls on a single slit of width 7.75 μm.Randomized Variablesλ = 598 nmw = 7.75 μm At what angle θ, in degrees, does it produces its second minimum?Numeric : A numeric value is expected and not an expression.θ = __________________________________________
