) A Michelson interferometer uses light whose wavelength is known to be 602.446 nm. Mirror M2 is slowly moved while exactly 33,198 bright-dark-bright fringe shifts are observed. What distance has M2 moved? Be sure to give your answer to an appropriate number of significant figures.

Respuesta :

Answer:

The distance will be "10,000,001.1 cm".

Explanation:

The given values are:

Wavelength,

λ = 602.446 nm

Number of moved fringes,

n = 33,198

Now, consider an equation of interference,

⇒  [tex]2d=n\lambda[/tex] ...(equation 1)

On putting the estimated values in the above equation, we get

⇒  [tex]2d=33198\times 602.446[/tex]

⇒       [tex]=\frac{33198\times 602.446}{2}[/tex]

⇒       [tex]=\frac{20000002.3}{2}[/tex]

⇒       [tex]=10000001.1[/tex] cm
