The student developed the model above. Using the model, identify two potential wave phenomena that occur and are the reason behind why the student can only hear the train in front of the apartment complex.
A. The train can be heard more easily in front of the apartment complex because of reflection and interference. As the sound comes
from the train, the sound waves reflect off of the complex and interfere with each other increasing the amplitude of the wave to
make it easier to hear.
B. The train cannot be heard as easily in the park because of reflection and diffraction. The sound reflects off of the trees in the park
and diffract between the trees, this causes the waves to bend too much to be heard.
C. The train can be heard more easily in front of the apartment complex because of diffraction and refraction. The sound waves
diffract between the other buildings aiming them towards the apartment complex and then the sound refracts through the
apartment complex which makes it more difficult to hear in the park.
D
The train cannot be heard as easily in the park because of interference and reflection. The other buildings in front of the park cause
interference of the sound waves from the train and the trees in the park cause reflection making it too hard to hear the train.
