3- Using a Michelson, we want to measure the expansion coefficient of a rod. If we place the rod in such a way that one of the Michelson mirrors is connected to it and the next mirror is completely fixed, the fringes will change as the rod is heated and enlarged. If the length of the rod is 20 cm and its expansion rate is 50 micrometers due to a temperature change of 50 degrees, what is the expansion coefficient of the rod (the wavelength of light is 500 nm) how many times does the central fringe move (brighten and darken)?

Question
Transcribed Image Text:3- Using a Michelson,
we want to measure the
expansion coefficient of
a rod. If we place the rod
in
such a way that one of
the Michelson mirrors is
connected to it and the
next mirror is
completely
fixed, the fringes will
change as the rod is
heated and enlarged. If
the length of the rod is
20 cm and
its expansion rate is 50
micrometers due to a
temperature change of
50 degrees, what is the
expansion coefficient of
the rod (the wavelength
of light is 500 nm) how
many times does the
central fringe move
(brighten and darken)?
