B  As the light traveled through the double slit, actual waves of water began to flow from the other side onto the screen.

C  The image formed on the screen showed the same constructive and destructive interference pattern associated with waves interfering with each other.

D  The image formed on the screen showed one single bright fringe in the center of the screen.

A  light behaves like a wave.

D  light can behave like a particle.

A  Light collecting isn’t important actually, since different wavelengths refract differently through a lens.

B  Light collecting isn’t important actually, since the eye piece magnifies the image.

C  Light collecting is important because it helps show the size of the planet or star.

D  Light collecting is important, because it makes faint objects visible.
