Consider a single slit that produces a first-order minimum at 16.5° when illuminated with monochromatic light. show answer No Attempt 50% Part (a) At what angle, in degrees, is the second-order minimum?

Explanation:

Path difference for the destructive interference of a single slit:

For the first - order minimum, n = 1, and

.........(1)

For the second - order minimum, n = 2,  and

.........(2)

Dividing equation (2) by equation (1):

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it
