- According to the inverse square law of light, how will the apparent brightness of an object change if its distance to us doubles? Its apparent brightness will decrease by a factor of 2. Its apparent brightness will increase by a factor of 4. Its apparent brightness will increase by a factor of 2. Its apparent brightness will decrease by a factor of 4.To what extent do astronomers have the ability to see into the history of the universe?Choose the BEST answer to the following: If a star that is 20 light-years from Earth explodes, gravitational waves from the explosion would reach Earth in (a) less than 20 years. (b) 20 years. (c) more than 20 years. (d) None of these.
