جهاز مايكلسون للتداخل

[فيزيائية ولكن]

السلام عليكم ورحمة الله وبركاته

عندي كم سؤال في تجربة مايكلسون للتداخل بليز أبي الأجابات بسرعة
السؤال الأول

[justify]
A Michelson interferometer using light of wavelength l has been adjusted to
produce a bright spot at the center of the interference pattern. Mirror M1 is
then moved distance l toward the beam splitter while M2 is moved distance l

away from the beam splitter. How many bright-dark-bright fringe shifts are
seen:
1. 0
2. 1
3. 2
4. 3
5. 4

[/justify]

السؤال الثاني:

Here’s another question on the Michleson and Morley Experiment: When
there’s no light on the viewing screen, we have light going into the
interferometer, but no light coming out. What happened to the light


السؤال الثالث:

Calculate the minimum spacing between the plates of a Fabry Perot
interferometer which would resolve two lines with

 = 0.1°A at



o= 6000°A. Assume the reflectivity to be R = 0.8
(Hint: Two wavelengths are just resolved if the half intensity point of one
of them falls on the half intensity point of the other.)
