Hello all,
General Relativity predicts that when a light ray leaves the ground a=
nd rises
higher its frequency gets smaller (i.e., light is redshifted). The Ro=
und &
Rebka (1960) experiment confirmed the prediction. On the other hand c=
locks run
more slowly in the precence of gravity. This is related to the gravit=
ational
redshift since atomic oscillations which emit the radiation can be vi=
ewed as
accurate clocks.
Here comes my question: I understand that the frequency of light (or =
any
electromagnetic wave) decreases when it "climbs" higher from the grou=
nd. This
means that period of the wave motion increases. Is there a way to "se=
e" that
this (decrease in f, increase in T) implies that time passes faster a=
t higher
altitude? For some reason I can't see it :-). Could you come up with =
an
explanation which would be suitable at the high school level?
Regards,
Antti
