WebThis example problem demonstrates how to find the energy of a photon from its wavelength.To do this, you need to use the wave equation to relate wavelength to frequency and Planck's equation to find the energy. This type of problem is good practice at rearranging equations, using correct units, and tracking significant figures. WebSep 20, 2024 · Wavelength ( λ) = 620 nm Speed of light ( c) = 3.00 × 10 8 m/s Conversion factor 1 m = 10 9 nm Unknown Frequency Convert the wavelength to m, then apply the equation c = λ ν and solve for frequency. Dividing both sides of the equation by λ yields: ν = c λ Step 2: Calculate. 620 nm × ( 1 m 10 9 nm) = 6.20 × 10 − 7 m

WebFor Pipe C, the frequency can be determined from knowledge of the speed and the wavelength using the wave equation: v = f • λ where λ is the wavelength. First, rearrange the equation. Then substitute and solve as shown below. f = v / λ = (340 m/s) / (0.64 m) = 531 Hz WebFeb 28, 2024 · Using a spectrophotometer, obtain a measurement for absorbance, A, at a given wavelength. The unit for wavelength is meters, but most wavelengths are so small, they are actually measured in nanometers (nm). [9] Absorbance has no units. 4 Plug in the values for the variables and solve the equation for molar absorptivity. Web1 Answer Sorted by: 2 v r = c ( λ − λ 0 λ 0), where λ is the observed wavelength and λ 0 is the wavelength at rest. This gives an equivalent velocity with respect to the central wavelength of the line. ina shastri
