this is because loudness of the sound depends on its amplitude so if the amplitude increases then the sound is loud and if the amplitude is decreased then the sound is relatively softer. in the same way if the frequency is increased then the sound is high pitched and if the frequency decreases the sound is low pitched.
Q. What happens to sound if the frequency of the vibrations increases?
If the frequency of a wave is increased, what happens to its wavelength? As the frequency increases, the wavelength decreases.
Q. What happens to sound when amplitude is high?
The sound is perceived as louder if the amplitude increases, and softer if the amplitude decreases. As the amplitude of the sound wave increases, the intensity of the sound increases. Sounds with higher intensities are perceived to be louder. Relative sound intensities are often given in units named decibels (dB).
Q. Why does high frequency travel more distance?
In the same medium, all sound waves travel at the same speed. Consequently, a sound wave can only propagate through a limited distance. In general, low frequency waves travel further than high frequency waves because there is less energy transferred to the medium.
Q. What are the two main properties of sound?
The two main properties of sound are frequency and amplitude. The frequency of the sound waves determines the pitch of the sound. The amplitude of sound determines the loudness. The quality of sound is affected by the pitch and the loudness.
Q. Which is the best description of a sound wave when the pitch of the sound is very high?
Which is the best description of a sound wave when the pitch of the sound is very high? It has a low frequency.
Q. Which wave behavior do noise Cancelling headphones use?
A noise-cancellation speaker emits a sound wave with the same amplitude but with inverted phase (also known as antiphase) to the original sound. The waves combine to form a new wave, in a process called interference, and effectively cancel each other out – an effect which is called phase cancellation.
Q. What is most true about sound waves?
TRUE – A sound wave transports its energy by means of particle interaction. A sound wave cannot travel through a vacuum. This makes sound a mechanical wave. FALSE – Only electromagnetic waves can travel through a vacuum; mechanical waves such as sound waves require a particle-interaction to transport their energy.
Q. What do sound waves travel through the fastest?
Of the three phases of matter (gas, liquid, and solid), sound waves travel the slowest through gases, faster through liquids, and fastest through solids.
Q. What applies to sound waves?
Sound is a longitudinal wave which consists of compressions and rarefactions travelling through a medium. Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed. The minimum distance in which a sound wave repeats itself is called its wavelength.
Q. What do you call the measurement for sound intensity?
We measure sound intensity (also referred to as sound power or sound pressure) in units called decibels. Decibels (dB) are named in honor of Alexander Graham Bell, the inventor of both the telephone and the audiometer.
