the picture shows marco listening to music from a speaker in an adjoining room. why can marco hear the music, even though he is not in the same room as the speaker? a. the sound is being reflected around the corners of the doorway. b. the sound is being refracted around the corners of the doorway. c. the sound is being absorbed around the corners of the doorway. d. the sound is being diffracted around the corners of the doorway.
Answer
# Answer:
D. The sound is being diffracted around the corners of the doorway
# Explanation:
## Step1: Recall wave - behavior concepts
Sound is a wave. Reflection is bouncing back of waves, refraction is bending due to medium change, absorption is energy loss, and diffraction is bending around obstacles.
## Step2: Analyze the situation
Marco can hear the music from the adjacent room. Sound waves are bending around the corners of the doorway (an obstacle), which is diffraction.
