If a pendulum makes 32 vibrations what is its frequency?
This question needs more info: Do you mean 32 swings per minute?
A pendulum makes 36 vibrations in exactly 60swhat is its period?
The frequency is (36/60) per second.The period is the reciprocal of the frequency = (60/36) = 1-2/3 seconds
How do sounds differ from one and and another?
it differs by the vibrations
What makes the diffrent sounding pitches on a stringed instrument?
Pitch is related to the frequency of the vibration. Frequency means the number of vibrations per second that a given string is tuned to produce. Today in most applications 'standard' pitch is centered around A=440, which means that a frequency of 440 cycles per second gives the musical pitch A.
What is the number of back and forth swings a pendulum makes is called?
If you mean the time it takes to swing from start to finish (top to top) this is called the period and if it is the number of swings per second this is know as the frequency.
What does it mean to say that the frequency of a wave is 25 hertz?
It means the the wave has a speed of 25 vibrations per second
What happens to the sound an object makes when the speed of vibrations decreases?
When the speed of vibrations decreases, the pitch of the sound produced by the object lowers. This is because the frequency of the vibrations decreases as well. As a result, the sound becomes deeper or lower in tone.
The number of oscillations a wave makes each second is the wave's?
Frequency.
Why does it makes sense to introduce the frequency of a wave as a part of a wave?
The frequency defines the repetition rate per second of the wave.
What is the number of oscillations that a light wave makes per second called?
The frequency of the wave.
How sound is formed?
sound is a form of energy that produces a sensation of hearing in our ears. Sound is produced by a vibrating body. When we strike a pan , or play the guitar vibrations are produced which produce sound. The vibrations that are produced sometimes we can see them , sometimes we cannot . If we throw a stone in a pond we hear a splashing sound and the ripples of the water can be seen , however when a pan is struck the vibrations may not be visible to us. Two important things to remember are-Amplitude and Frequency. Amplitude-the maximum extent a vibration can go to from its mean position. Frequency-the number of oscillations by a vibrating body in a second. Unit of frequency is Hertz (Hz).
Nobody is sure how Felis silvestris catus makes this sound and we're not even sure why but we do know that the vibrations reduce stress in people and that they occur at a frequency that helps bones?
