Two light sources emit waves that are in phase with a wavelength of λ = 250 nm. the two waves meet at a distant point where wave #1 has traveled 100 nm. the distance traveled by wave #2 is variable. which of the distances for wave #2, listed below, would result in destructive interference? a. 600nmb. 300nmc. 975nmd. 500nme. 475nm

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

i had this question and the answer was 3.15 miles.
