Monochromatic light is incident on a pair of slits that are separated by 0.220 mm. The screen is 2.60 m away from the slits. (Assume the small-angle approximation is valid here.) (a) If the distance between the central bright fringe and either of the adjacent bright fringes is 1.97 cm, find the wavelength of the incident light.
(b) At what angle does the next set of bright fringes appear?

a

b

Explanation:

From the question we are told that

   The distance of separation is

    The  is distance of the screen from the slit is  

    The distance between the central bright fringe and either of the adjacent bright  

Generally  the condition for constructive interference is  

From the question we are told that small-angle approximation is valid here.

So    

=>        

=>        

Here n is the order of maxima and the value is  n =  1 because we are considering the central bright fringe and either of the adjacent bright fringes

Generally the distance between the central bright fringe and either of the adjacent bright  is mathematically represented as

From the question we are told that small-angle approximation is valid here.

So

=>  

So

substituting values

In the b part of the question we are considering the next set of bright fringe so  n=  2

    Hence

anchor = archer //

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
