Whether the statement is true or false.
Answer to Problem 1QAP
The given statement is false.
Explanation of Solution
Light travels at a speed of
Such large distances are measured in units of light years denoted by
Here, the distance given is
Conclusion:
Thus, one mega-light-year is not equal to 1,000 light years. Hence, the given statement is false.

- If the speed of light is 3.0 × 105 km/s, how many kilometers are in a light-year? How many meters? (Hint: First look up or calculate how many seconds are in a year.)arrow_forward1 million kilometers can be expressed in scientific notation as: 10x10^6 km 10x10^-6 km none of these 1x10^6 km 1x10^-6kmarrow_forwardIn 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.arrow_forward
- If the speed of light is given as 299,792,458 meters per second and the wavelength is 478 nm. what is the frequency of this light? Give your answer in THz!arrow_forwardWhat is the distance in meters to our Sun that is 500 light-seconds away?arrow_forwardT/ F The distance unit best for interstellar distances is the light-year. ___ The distance unit best for intergalactic distances is the mega-parsec. ___arrow_forward
- (a) Astronomers use a special unit to measure distances called astronomical unit (AU) where 1 AU is defined as 92,955,807 miles. They also use another unit called parsecs where 1 parsec is equal to 206,264.4 AU. Convert 1 Zm (zettametre) into kiloparsecs. (Given 1 mi = 1.609 km; 1 km = 1000 m).arrow_forwardThe average Earth–Sun distance is about 149,600,000 km. To represent this distance to scale, how far away would you have to place your 3-inch Earth from your Sun?arrow_forwardHuman civilization is about 10,000 years old as measured by the development of agriculture. If your telescope collects starlight tonight that has been traveling for 10,000 years, is that star inside or outside our Milky Way Galaxy? Is it likely that the star has changed much during that time?arrow_forward
- Why are light-years more convenient than miles, kilometers, or AU for measuring the distances to stars and galaxies?arrow_forwardThe closest star to Earth, after the Sun, is Proxima Centauri, which is just over 4 light years away from us. A light year is the distance traveled in one year by light, which travels at about 300,000 kilometers per second. What is the order of magnitude of the number of kilometers that separate us from Proxima Centauriarrow_forwardHow long would it take a space craft that was traveling at a speed of 61,079 km/hr to travel a distance of 116 lightyears?arrow_forward
