what is sound?
how many types of sound r there?
Answers
Answer:
sound is occurred when two metals or non metals collide with each other producing vibrational waves, we are hearing that is names by sound. types: pitch, echo, amplitude,
Answer:
⇒Sound is a pressure wave which is created by a vibrating object.
⇒Wavelength – A sound wave is created due to pressure variations caused by vibrations. There are low pressure areas and high pressure areas. The high pressure areas are represented as crests and low pressure areas as troughs.
⇒The physical distance between two consecutive crests or troughs in a sound wave is referred to as a wavelength.
⇒Amplitude – In sound waves, amplitude refers to the magnitude of compression or expansion experienced by the medium the sound wave is travelling through.
⇒High amplitude means loud noise. Low amplitude means low sound.
⇒Pitch – Pitch/Frequency in a sound wave refers to the rate of the vibration of a particular sound travelling through air. It is calculated in cycles per second. The SI Unit for Frequency is Hertz.
