Light Waves

bending of light that happens when light travels through different mediums (substances)

• reflection

• refraction

• diffusion

When light bounces off an object- If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface.

• reflection

• refraction

• diffusion

the height or depth of a wave that determines how much ENERGY the wave carries. In a sound wave, it is also synonymous with how much volume the wave carries.

• wavelength

• compression

• amplitude

a mechanical wave that moves parallel or back and forth to the direction of wave travel

• wave

• medium

• transverse wave

• longitudinal wave

Which statement best describes what waves are?

• wavy lines on graph paper

• disturbances that transfer energy

• circles that move out from a central place 

The light we can see. 

• visible

• gamma

• ultraviolet

The highest point on a wave

• trough

What is reflection in simple terms?

• Soaks up light

• Passes through

• light bounces off

What does refract mean?

• To shrink

• To bend
