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

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

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

D  This sounds like a supernatural phenomenon… I don’t think this would have happened. Like, ever.

A  light only behaves like a particle, and not like a wave.

B  light behaves like a wave.

C  light can behave like a particle.

D  light only behaves like a wave, since the photoelectric effect experiment failed.

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

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

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

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

A  A magnifying lens focusing light.

B  A floodlight shining light over a wide area.

C  A telescope focusing light to produce an image.

D  A lens refracting the incoming waves of color at different angles.

A  all of these
