Open Ended

If light is color, why do these two universes (light and pigment) follow completely opposite rules?

Multiple Choice

What is the shortest distance between points where the wave pattern repeats itself called?

• Wavelength

• Amplitude

• Frequency

• Period

Multiple Select

Which statements about Huygens' wavelets and diffraction are correct?

• Every point on a wave front acts as a new source.

• Wavelets combine to form a straight wavefront except at the edges.

• Wavelets spread out in a circular manner at the edge, causing light to bend.

• Wavelets always travel in a straight line regardless of barriers.

Open Ended

Explain how light behaves when it encounters the edge of a barrier, referencing the concept of diffraction.
