False. The unit of the period of a wave is seconds, not hertz. Period is the time it takes for one complete cycle of the wave, while hertz represents the frequency of the wave, which is the number of cycles per second.
false!!
Yes, indeed it is. An astronomical unit is 8.3 light minutes. So light years are indeed a unit of time used in space, but not in our solar system, because our solar system is not big enough to use light hours. An astronomical unit, by the way, is the distance from the sun to Earth.
It is a unit of time and distance. A light year is the amount of time it takes for a beam of light to travel through space in one earth year, which is 5.9 trillion kilometers. Time : one year, distance : 5.9 trillion km.
