Presentation Transcript

    1. If the hydrogen Balmer alpha line has a rest wavelength of 656.3 nm, and you observe it in a star moving away from us at 600 km/s, use the Doppler shift formula to find the observed wavelength of the line. 656.3 nm 657.6 nm 655.0 nm 658.3 nm 653.7 nm

    2. A spectrum of a star is an example of Kirchhoffs 1st law a hot body (solid, liquid, or dense gas) will emit a continuous spectrum. Kirchhoffs 2nd law A low density gas excited to emit light will do so at specific wavelengths, producing an emission spectrum. Kirchhoffs 3rd law If light comprising a continuous spectrum passes through a cool, low density gas, the result will be an absorption spectrum.

    33. Natures 4 Forces 1. Gravity (weakest; acts over large distances) 2. Electromagnetism (radiation) 3. Weak Nuclear Force (causes decay neutrons and protons) 4. Strong nuclear force (binds protons and neutrons in nuclei together; acts over very small distances only)

    34. Energy Production

    35. Einsteins famous equation E=mc2 says that energy and matter (mass) are equivalent and interchangeable. Suppose you were to convert the mass of m=1 kg (about the mass of your textbook) to energy. How much energy would you get? E(Joules)= mc2 (c=3x108 m/s) Now, if Wyoming uses 8.1x1016 Joules (2.25x1010 kiloWatt hours) per year, how long would this supply the state? A. 0.1 years B. 1 year C. 10 years D. 100 years
