A parsec is an astronomical unit of distance where 1 parsec = 3.26 light years (1 light year equals the distance traveled by light in one year). If the speed of light is 186,000 mi/s, calculate the distance in meters of an object that travels 3.9 parsecs.

4. Speed of Light. Light travels through space at an incredible speed, 186,282 miles per second. How far does light travel through space in one hour? (This is the speed of light in miles per hour.) How far does light travel in one year? (This distance is a light-year.) 5. Interplanetary Communication. The average distance between the planet Mars and the Earth is 100 million miles. We communicate with robots on Mars with radio...

Some observations reported on an astronomical object (quasar 3C-9) suggest that, when it emitted the light that has just reached the earth, it was moving away from the earth at a speed of about (4/5),c (a) One of the lines identified in its spectrum has a wavelength of about 1200 A when emitted from a stationary source. At what wavelength must this line have appeared on the observed spectrum of the quasar? (Note: 1 Å= 10-10 m and c =...

f) in vacuum, light travels at about 186,282 miles per second. One mile is about 161 kilometers (km). Astronomers prefer to use units of distance that are reasonable in describing how far objects are from Earth. For example, for distances in the solar system we use the astronomical unit (AU), which is equal to the average distance of Earth from the Sun; 1 AU is about 150 million km. For distances to stars and galaxies, astronomers use the light-year (1...

If you don't solve this problem correctly in 3 tries, you can get a hint. Use the angular resolution for the Hubble Telescope to determine the smallest detail which it can observe on the moon, if the moon is 3.82 x 10 m away. Assume an average wavelength of 500 nm, and that the telescope's diameter is 2.40 m. The headlights of a car are 1.14 Vm apart. What is the maximum distance at which the eye can resolve these...

1. If an alien civilization is located 60 light-years away and they detect the earliest Earth tv transmissions (from ~1930), what year should we receive the first message from the aliens? How did you arrive at your answer? 2. Assume you wanted to have a discussion with a civilization located near the center of the Milky Way Galaxy. What would be the minimum time between sending the signal and receiving a reply? we live about 2.5x10^20 meters from the center...

a) Using s = rθ, calculate the arc length (in meters) subtended by the sun when it moves an angular distance of 2 x10-6 °. The distance between the Earth and Sun is called an AU (astronomical unit). 1 AU = 1.5 x1011 m. (Don’t forget to convert to radians). As you can see from the above calculation, a small change in angle can correspond to a large distance. In astronomy angles are typically measured in arcminutes or arcseconds 1...
