Question
.Identify the correct/incorrect statements among the following.(i) Sound waves are longitudinal in nature.(ii) The speed of sound in distilled water is more than the speed of sound in sea water.(iii) Large amplitude of sound waves will produce louder sound.(iv) When you increase the loudness of the ringtone of your mobile phone, the frequency ofring tone decreases.
Solution
(i) Sound waves are longitudinal in nature. - Correct statement. Sound waves are indeed longitudinal waves, meaning that the particles of the medium vibrate parallel to the direction of wave propagation.
(ii) The speed of sound in distilled water is more than the speed of sound in sea water. - Incorrect statement. The speed of sound is generally higher in sea water compared to distilled water due to the difference in density and other factors.
(iii) Large amplitude of sound waves will produce louder sound. - Correct statement. The amplitude of a sound wave determines its loudness. A larger amplitude corresponds to a louder sound.
(iv) When you increase the loudness of the ringtone of your mobile phone, the frequency of the ringtone decreases. - Incorrect statement. Increasing the loudness of a sound does not affect its frequency. The frequency of a sound wave corresponds to its pitch and remains constant regardless of the loudness.
