Unit: Waves
Year: 1991 Question#: 52
Question: In the diagram below, two speakers are connected to a sound generator. The speakers produce a sound pattern of constant frequency such that a listener will hear the sound very well at A and C, but not as well at point B. Which wave phenomenon is illustrated by this experiment?
(1 ) interference
(2 ) polarization
(3 ) reflection
(4 ) refraction

Answer 1
interference
CORRECT
interference is correct because interference is the overlapping of two or more waves that arrive in a region at the same time. return to top
Answer 2
polorization
INCORRECT
polorization is the filtering out of all vibrations in a transverse wave that are not in a given direction. (ex.)

Answer 3
reflection
INCORRECT
reflection is when a particle or wave bounces off of an object such as a light beam bouncing off of a mirror. return to top
Answer 4
refraction
INCORRECT
refraction is the change of direction when a wave moves from one media to another such as a light wave hitting the water and making the water seem shallower than it is. return to top
