Physical Science

What causes our sunrises and sunsets to appear red and orange?

• refraction of light through cold air

• reflection of light through cold air

• refraction of light through hot air

• small particles scatter shorter blue wavelengths more than red-orange so we see more red-orange

How do sunglasses work?

• Gradually refracting light as it passes through the lenses

• Bending light as it passes from air into the lenses

• Blocking light waves that vibrate in one plane

• Reflecting most of the light that strikes the sunglasses

How do sunglasses work?

• Polarized sunglasses absorb all light coming in

• polarized sunglasses have horizontally polarized filters to block the horizontally polarized light.

• polarized sunglasses have vertically polarized filters to block the horizontally polarized light.

• polarized sunglasses have vertically polarized filters to diffract the horizontally polarized light.

• opaque

• translucent

• transparent

What are the three light transmitting capabilities?

• reflective, refractive, diffractive

• converse, inverse, diverse

• direct, indirect, codirect

• transparent, translucent, opaque

An object that allows NO light to pass through which creates a shadow behind the object

• opaque

• transparent

• translucent

• translated

What type of reflection of light would occur on a lake with high waves?

• regular

• diffuse

• irregular

• instantaneous
