In a double-slit arrangement the slits are separated by a distance equal to 150 times the wavelength of the light passing through the slits. (a) What is the angular separation between the central maximum and an adjacent maximum

Complete  Question

In a double-slit arrangement the slits are separated by a distance equal to 150 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 57.9 cm from the slits?

a

b

Explanation:

From the question we are told that

    The slit separation is  

    The  distance from the screen is  

Generally the condition for constructive interference is mathematically represented as

=>        

where  n is the order of the maxima  and value is 1 because we are considering the central maximum and an adjacent maximum

     and   is the wavelength of the light

So

Generally the distance between the maxima is mathematically represented as

=>    

=>    

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .

im srry but ur wrong the answer is d a smooth rock, some red dirt, and an empty bird's nest.
