Behavior of Light

Refraction is:

• Bending of light

• Bouncing of a light wave

• Light waves are not able to travel without a medium

Reflection is:

• Bending of light

• Light waves are not able to travel without a medium

• Bouncing of light

Why do objects underwater look closer than they actually are?

• absorption

• reflection

• refraction

• diffraction

A prism separates white light into

• light particles of wave matter

• other dimensions

• colorized matter or independent particle matter waves

• the visible light spectrum

Diffraction is

• The bending of waves around or through barriers

• the bending of light in a group over barriers

• the bending of light over time and space

• the refraction of light through a prism

constructive interference results in:

• a combined wave with greater amplitude = brighter light

• different colors appearing the same with same amplitude

• a combined wave with a smaller amplitude = dimmer light

• not being able to see light with low amplitude

A light source

• gives off its own light

• gives light that is reflected

• gives off reflective light that is refracted

• gives off refracted light that is reflected

A reflected source

• gives off its own light

• gives light that is reflected

• gives off refracted light that is reflected

• gives off reflected light that is refracted

We can see mars at night because

• it is reflecting Earth's ambient light

• it is a light source like our moon is

• it is reflecting the sun because it is a reflective light source

• light is scattered not diffracted - as it is through rain

When energy carried by light waves is transferred to particles of matter it is called

• refraction

• reflection

• optimal warming

• absorption
