Concept explainers
To choose:The correct option which states,the waythrough which sound travels from its source to the ear.
Answer to Problem 1STP
The answer is option A- by changes in air pressure.
Explanation of Solution
Introduction: Sound waves travel through the ear canal (a narrow passageway)by entering the outer ear, and it further leads to the eardrum.
The eardrum pushed back and forthwhen sound travels down the narrow passageway that is the ear canal. The eardrummoveswith the change in air pressure. The movements of the ear drum are very small and since the inner ear
Conclusion: The way through which sound travels from its source to your ear is by changes in air pressure.
