Pitch of sound depends upon
The number of vibration per second is called frequency. The pitch of sound depends upon frequency of sound.
Sound helps us to
Sound helps us to communicate with one another. We share our views and suggestions with others either by sound or through written medium.
Sound is produced by
Sound is produced by vibration of object. Vibration creates disturbance in medium which reaches to observer ear through air, water or solid medium.
Speed of sound increase with
Speed of sound increase with increase in temperature. During propagation of sounds particles of medium travel faster at higher temperature.
When a tightly stretched band is plucked it
When a tightly stretched band is plucked it vibrate and produce sound due to disturbance in medium.
Which of the following factor influence speed of sound most?
Speed of sound depends upon nature of medium, temperature, humidity and source of sound but nature of medium influence the speed of sound most. Sound travels faster in solid medium than air and water.
Which of the following require material medium for propagation?
Sound requires material medium for its propagation which may be solid, liquid or gaseous in nature. Light can travel in vacuum as no medium is required.
Yes sound waves always need a medium to propagate like metal,liquid,or air .Therefore in space no medium is present that is why sound does not travel in space.
In most of the cases vibration of objects are not visible because
The vibrations of object are not visible because in most of the cases amplitude of waves are very small. Amplitude is the maximum displacement from mean position.
Loudness of sound depends upon its
The maximum displacement from mean position is called its amplitude. The loudness of sound depends upon its amplitude.
Vibrating part of flute is
Sound is produced by vibration of body. In flute, the vibrating part is air column inside the flute.
