Red light produces interference through two narrow slits spaced a distance 0.0050 cm apart. In air this light has a wavelength of 650 nm.

1. [2pt]
At what distance from the slits should we place a screen so that the first few interference brights are spaced
1.0 cm apart? (Be sure to use a consistent set of length units... All meters or all centimeters.)

In a system, when potential energy decreases, then entropy also decreases. true false

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
