Know angular momentum equationoL= m*v*rConsequences of earth rotation (hurricanes etc.)Theory of relativity. results of Einstein’s experiment space vs time. energy vs mass. whyastronauts are weightless in spaceSpeed of lightWavelengths of light.. visible bend and the rangesApprox. wavelengths know and which order are they increasing in wavelength andfrequencyWavelength of light and photons are equal in describing.. **energy of a photon**Speed of light= wavelength * frequencyElectrons and protons are not just arranged in some arbitrary formation like planets…electrons are in very definite orbits and can jump up and down only with the specificamount not in-betweenTemperature and color.. temp scale know Kelvin.. all relative to 0 degrees

Unformatted text preview: Surface temperature of the sun: 5600K.. emits energy and it would be color yellow Temp color and energy coalition are related Brightness decreases to square of the distance… grav force and electromagnetic force follow same type of equation 4(pie)r^2 Colors aren’t focused properly is why we don’t build big telescopes with big lenses anymore… chromatic something… ends up blurring the image Mirror on other hand reflects the colors right on C=(wavelength)(f) E=hf=hc/(wavelength) 6562 Angstroms 3 2 red If body went up temperature 2 times, the energy would go up by a factor of 16 As distance increases, brightness decreases by squaring its number...
