Why Is Light Affected By Gravity?
In astronomy, distances are often expressed in light-years. One light-year is the distance traveled by light in one year. If the distance to a star is 5.9 light-years, what is this distance in meters? (There are 365.25 days in one year.)
In astronomy, distances are often expressed in light-years. One light-year is the distance traveled by light in one year. The distance to Alpha Centauri, the closest star other than our own sun that can be seen by the naked eye, is 4.3 light-years. Express this distance in meters.
