5.4 - Standing Waves and Resonance

Question 1

The place where two mediums meet is
called a

Answer 1

media boundary.

Question 2

When a wave in one medium encounters
a “_____ ____” (or a less dense material) it
will be reflected exactly as it went out.

Answer 2

free end

Question 3

When a wave in one medium encounters
a “_____ ____” (or a more dense material)
it will be inverted upon reflection.

Answer 3

fixed end

Question 4

Because waves reflect when they
encounter a media boundary, it is
possible for a wave to create an
interference pattern with itself.

One possible result is something called a
____________

Answer 4

standing wave pattern.

Question 5

______ are points in a medium that are
continuously at rest, and occur in places
where complete destructive interference
occurs.

Answer 5

Nodes

Question 6

interference occurs are called _______.

Answer 6

antinodes

Question 7
