Why can’t we see star in day time?
Two stars have the exact same luminosity, but star Y is four times dimmer looking that star X. This means that????
1)
star Y is four times as far away as star X

star Y is 16 times as far away as star X
3)
star Y is half as far away as star X
4)
star Y is twice as far away as star X
5)
we can't figure out the relative distance of the two stars from the information given

- A star has an element in its atmosphere that normally emits a line of frequency fs = 7.5 x 10^14 vib/s. If astronomers measure the frequency of this line to be fo = 7.7 x 10^14 vib/s, then how fast are the Earth and this star traveling relative to each other? Remember that the correct equation for the speed v is given by v = [(fo^2 - fs^2) / (fo^2 + fs^2)] c Remember fo^2 means "fo squared."arrow_forwardWhat is the difference in magnitude for two stars is one appears four times brighter than the other?arrow_forward
