How might an astronomer use the knowledge of refraction? How might an astronomer use the knowledge of refraction? Solution An Astronomer would use the knowledge of refraction of light to know that light bends its path when it cahnges its medium like when it travells from vacuum into air. This knowledge will help the astronmer to estimate more accurate and precise locations of sun or planets by figuring out how much the light would have bent and how farther the celestial body is from its apparent position (because of the refraction) .

Solution
An Astronomer would use the knowledge of refraction of light to know that light bends its path
when it cahnges its medium like when it travells from vacuum into air. This knowledge will help
the astronmer to estimate more accurate and precise locations of sun or planets by figuring out
how much the light would have bent and how farther the celestial body is from its apparent
position (because of the refraction)
