Monochromatic light falls on a slit that is 2.30×10−3mm wide. part a if the angle between the first dark fringes on either side of the central maximum is 34.0 ∘ (dark fringe to dark fringe), what is the wavelength of the light used?

Wavelength,

Explanation:

Given that,

Width of the slit,

The angle between the first dark fringes on either side of the central maximum is 34 degrees

To find,

The wavelength of the light used.

Solution,

The equation of maxima is given by :

n = 1 here

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

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
