1. Mars orbits the Sun once every 1.88 years. Find the average distance of Mars from the Sun.
2. Two stars of mass 2Ms und 5Ms orbit each other at a distance of 1.5 x 10^10 m. Find the orbital period.
3. Jupter's moon Io orbits the planet with a period of 1.769 days at a distance of 4.22 x 10^8 km. Find the mass of Jupiter.
4. Find the frequency (in Gigahertz) of light of wavelength 3.0 cm.
5. Find the wavelength (in nanometers) of light of frequenc^18 MHz.
6. The wavelength of a characteristic spectral line in the spectrum of the star Betelguese has a wavelength of 656.212 nm. Lab measurements demonstrate that the normal wavelength of this spectral line is 656.285 nm. (A) Is the star coming towards us or away from us? (B) At what speed?
7. What is the wavelength of maximum intensity for an object at room temperature, T = 20 degrees C?
8. What is the energy of a photon of wavelength 656 nm?
i cant thats why im asking
