The yellow light from a sodium vapor lamp seems to be monochromatic, but it produces two distinct first-order maxima at 36.09° and 36.133° when projected through a 10,000 line per centimeter diffraction grating. a.What is the wavelength, in nanometers, producing the first maximum, to an accuracy of at least 0.1 nm? b.What is the wavelength, in nanometers, producing the second maximum, to an accuracy of at least 0.1 nm?

Light from a laboratory sodium lamp has two strong yellow components at 589.6 nm and 590.0 nm. This light falls normally on a transmission grating that contains 8000 lines per centimeter. a. Calculate the slits spacing in the diffraction grating. b. Calculate the angular separation between the first-order maxima of these two wavelengths. c. How far apart in the first-order spectrum will these two lines be on a screen 1.2 m from the grating?

A yellow light technically means to stop but many people ignore it and drive through. It is thought that men are more aggressive drivers than women and are more prone to go through yellows. Experimenters stood by one traffic light at various times of the day and monitored a random sample of drivers. One experimenter took note of whether the driver stopped or went through the light and the other noted the gender. Here are the results: Drivers Percentage going...

When you shine a light on an object, the momentum from the photons that make up that light impacts the object. For macroscopic objects, this will have no measurable effect. Describe why this is different for atomic-sized objects. Suppose you shine a very long wavelength light on one electron and a very short wavelength light on another electron. What differences will you observe? Why does shining very short wavelength photons on an electron not tell you exactly where the electron...

Light from a fluorescent lamp is observed through a cloud of cool nitrogen gas. Again, two students are having a discussion about the kind of spectra that they would see. Student 1: We would see absorption line spectra and the missing lines would correspond to the light from the fluorescent lamp. Student 2: I disagree. We would see an emission line spectrum corresponding to nitrogen. This would happen because the nitrogen gas would absorb some energy from the fluorescent lamp...
