Question
Light of wavelength 550. nm is used to calibrate a Michelson interferometer. With the use of a micrometer screw, the platform on which one mirror is mounted is moved 0.180 mm. How many fringe shifts are counted?
Step 1
The wavelength of the light is given as 550 nm, which is equal to \(550 \times 10^{-9}\) m. The distance the mirror is moved is given as 0.180 mm, which is equal to \(0.180 \times 10^{-3}\) m or \(1.8 \times 10^{-4}\) m. Show more…

Light of wavelength $550 \mathrm{~nm}$ is used to calibrate a Michelson interferometer. With the use of a micrometer screw, the platform on which one mirror is mounted is moved $0.180 \mathrm{~mm}$. How many fringe shifts are counted?
Light of wavelength $550.5 \mathrm{~nm}$ is used to calibrate a Michelson interferometer, and mirror $\mathrm{M}_{1}$ is moved $0.180 \mathrm{~mm}$. How many dark fringes are counted?
Find the wavelength of light used in a Michelson interferometer if 550 bright fringes go by a fixed point when the mirror moves $0.150 \mathrm{mm}$.
