User: In a transverse wave that travels through a medium, the molecules of the medium vibrate A. with smaller amplitudes than the molecules in a longitudinal wave. B. at twice the velocity of the molecules in a longitudinal wave. C. in the direction in which the wave travels. D. at right angles to the direction in which the wave travels.

Weegy: B. at right angles to the direction in which the wave travels. Longitudinal waves vibrate the medium in the same direction as the propogation of the wave.

User: The function of the eardrum in the middle ear is to A. carry the sound energy to the brain. B. collect the sound waves. C. vibrate with the frequency of the received sound. D. amplify the received sound.

User: The function of the eardrum in the middle ear is to

Weegy: The function of the eardrum in the middle ear is to vibrate with the frequency of received sounds. The sound waves first pass through the outer auditory canal to the eardrum, causing it to vibrate. [ Then the vibrations of the eardrum go through a chain of bones in the middle ear to a sensory organ of the inner ear that sends them on to the brain through the auditory nerve. The brain then processes the nerve impulses and interprets them as specific sounds. ]

User: In which one of the following locations can a person hear the echo of a sound? A. At least 33.2 meters behind the reflecting surface B. Less than 33.2 meters behind the reflecting surface C. Less than 16.6 meters in front of the reflecting surface D. At least 16.6 meters in front of the reflecting surface

User: The part of the ear where sound wave compressions and rarefactions cause the eardrum to vibrate is the A. inner ear. B. auditory nerve. C. middle ear. D. outer ear.

Weegy: The part of the ear where sound wave compressions and rarefactions cause the eardrum to vibrate is the C. middle ear.
