What is the main difference between refraction and diffraction? A Refraction is a phenomenon that affects light; diffraction is a phenomenon that affects sound. B Refraction involves the bending of light; diffraction involves the bending and spreading of light, usually around an obstacle. C Refraction usually happens in the atmosphere; diffraction usually happens closer to the earth's surface. D Refraction involves changes to the density of light; diffraction involves changes to the speed of light.

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.
