Light from the Sun is something we all seem to take for granted, it’s always there, even at night we see its reflected glory from the Moon. It’s your choice whether you go out in the bright light of day or the soft moonlight of night to hunt down this cache, but before you head out please find the approximate light signal travel times for the following questions to work out the co-ordinates you will need.
A= Light travels from the Moon to the Earth in A.3 seconds
B= If light traveled from the sun to the Earth and back to the sun twice, it
would complete these cycles in approximately B2 minutes
C= Light travels the distance of the length of the Earth’s Equator
in 13C milliseconds
D=C+1
E= Ole Rømer demonstrated that light travelled at a finite speed in 16E6
G= The speed of light = 2GG,7G2.458 metres per second
(local inertial frames)
F = The number of times light would have circled the earth in 804ms
(if light could bend around corners)
H= Half the number of whole years it would take light to travel from
the nearest star to the Sun
