Answer 1

Answer:

b. refract sound waves

Answer 2

In auditorium, soft materials and carpets are used to absorb sound waves.

• In auditorium, the sound based performances are extremely common.
• Now, in a closed place like the auditorium, the sound produced from the stage may get reflected by the walls of the auditorium and may cause irritating reverberation.
• To avoid this unwanted reverberation, sound absorbing materials are applied on floor and walls, like carpets etc.
• These soft materials will absorb most of the sound waves before they get reflected back and prevents the occurence of the reverberation.
