What best describes the difference between the second sound wave and the first? ... The air molecules in the compressions of the second wave are more dense . The air molecules in the second wave are closer together on average, so they travel faster. The air molecules in the compressions of the second wave are more dense.
What is the difference between two sounds waves that have different pitches?
You can hear a difference between these two sounds. That is because their pitch is different. Pitch depends on the frequency of a sound wave. ... High sounds have high frequencies and low sounds have low frequencies.
What is the difference between the two sound waves?
The phase difference between two sound waves of the same frequency moving past a fixed location is given by the time difference between the same positions within the wave cycles of the two sounds (the peaks or positive-going zero crossings, for example), expressed as a fraction of one wave cycle.
What best describes a soundwave?
what best describes sound waves? a series of compressions and rarefactions, longitudinal pressure waves .
What are the 3 types of sound?
Sound waves fall into three categories: longitudinal waves, mechanical waves, and pressure waves .
Which do sound waves travel fastest through?
Sound waves can be described by the wavelength and frequency of the waves. Sound travels more quickly through solids than through liquids and gases because the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster.
Does higher pitch mean louder sound?
Children will often mix up pitch and loudness believing that a higher pitched sound is a louder one . Higher pitched sounds produce waves which are closer together than for lower pitched sounds. ... A smaller triangle or cymbal will make a relatively higher pitch note.
What are the three requirements of sound?
- A source – where the sound is made.
- A medium – something for the sound to travel through.
- A receiver – something to detect the sound.
What do you call the quality of sound?
Timbre , also called timber, quality of auditory sensations produced by the tone of a sound wave.
Which best describes Savanna's error?
Which best describes Savanna's error? The FM carrier waves should have different frequencies than the carrier waves , not different amplitudes. ... It will not capture modulated radio waves.
What best describes a possible transfer of energy?
What best describes a possible transfer of energy? A mechanical wave transfers energy through matter . ... A transverse wave transfers energy parallel to wave motion. A sound wave does not need a medium to transfer energy through.
Which is the best example of the wave phenomenon called transmission?
Which is the best example of the wave phenomenon called transmission? A street is seen through a window. Sound is heard around an open doorway. A coin seems smaller at the bottom of a swimming pool .
What is noise give example?
Noise is defined as a sound, especially a loud one. An example of a noise is the sound of fireworks . ... To noise is defined as to tell rumors or spread information around. An example of to noise is to gossip around town.
What are the 2 types of sound?
Sound has two basic forms: acoustic energy and mechanical energy . Each type of sound has to be tackled in their own way. Acoustic energy or sound is what we experience every day. It is in fact vibration of air (sound waves) which is transformed by the tympanic membrane in the ear of human to audible sounds.
What is that kind of sound called?
There are two types of sound, Audible and Inaudible .
Can sound waves travel in vacuum?
Sound waves are travelling vibrations of particles in media such as air, water or metal. So it stands to reason that they cannot travel through empty space , where there are no atoms or molecules to vibrate.
