PS M9 Test Review Introduction to Waves

a repeating disturbance or movement that transfers energy through matter or space

(a)  

anything that has mass and takes up space

(a)  

Diffraction occurs when waves (a)   around the edge of a barrier.

When light slows down as it passes from air to water it bends toward the (a)   .

Waves are rhythmic disturbances that carry energy through matter or space without transferring (a)   .

The angle between an incident ray and the normal is called the (a)   .

A (a)   is due to the interference of two traveling waves moving in opposite directions.

Refraction and (a)   both involve the bending of waves.

A line perpendicular to a reflection surface is called the (a)   .

In a compressional wave, the area where the particles are furthest apart is a (a)   .
