In a double-slit arrangement the slits are separated by a distance equal to 120 times the wavelength of the light passing through the slits. (a) What is the angular separation between the central maximum and an adjacent maximum

In a double-slit arrangement the slits are separated by a distance equal to 120 times the wavelength of the light passing through the slits. (a) What is the angular separation between the central maximum and an adjacent maximum(b) What is the distance between these maxima on a screen 5.79m from the slits?

a

b

Explanation:

From the question we are told that

   The  slit separation is  

Here is the wavelength of the light

   Generally the condition for constructive interference is  mathematically represented as

=>    

=>    

Here n is the order of maxima which is  1 given that we are considering the central maximum and an adjacent maximum

So  

=>    

Generally given that the distance of the screen is  D =  5.79 m from the slit then the distance between these maxima is mathematically represented as

=>      

=>      

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.

explanation:

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
