The wavelength of a monochromatic source is measured with a michelson interferometer. an interference pattern is viewed on the screen. when the movable mirror moves d = 0.14 mm, 460 fringes move past a fixed point on the screen. what is the wavelength of the light in nm?

Wavelength of light is 608 nm.

Explanation:

It is given that,

Distance associated with the fringes, d = 0.14 mm = 0.00014 m

Number of fringes, m = 460

We need to find the wavelength of the light. In Michelson interferometer, the distance associated with the fringes is given by :

So, the wavelength of the light is 608 nm. Hence, this is the required solution.

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
