Show the complete proof for the BAC-CAB rule on a separate sheet of paper by evaluating both sides of the equation and showing that both sides are equal. Make sure to show your neat and complete solutions.

Let , , and represent three non-null vectors. The vector triple product is

 

x ( x ) = ( ) - ( )

 

This formula is also known as the BAC-CAB rule.

 

Light of wavelength 585 nm falls on a slit 0.0666 mm wide. (a) On a very large and distant screen, how many totally dark fringes (indicating complete cancellation) will there be, including both sides of the central bright spot? Solve this problem without calculating all the angles? (Hint What is the largest that sin u can be? What does this tell you is the largest that m can be?) (b) At what angle will the dark fringe that is most distant from the central bright fringe occur?

can sombody help me to resolve a complete solution for this probleme ?
