Which among the following is true?a) Amplitude the distance travelled ...
Ans: b
Explanation: Amplitude – the maximum displacement on one side of mean position of a particle of medium, is called the amplitude of the wave.
Time period -the time taken by a particle of the medium to complete its one vibration in called the time period of the wave.
Frequency -the number of vibrations made by a particle is called the frequency of the wave.
Wave velocity - the distance travelled by a wave in one second is travelled by a wave in one second is called wave velocity.
Wavelength - the distance travelled by a wave in one time period of a medium is called its wavelength.

Which among the following is true?a) Amplitude the distance travelled ...
The number of vibrations of the medium particle per second is called as the frequency of sound wave. For example if a particle of medium undergoes 200 vibrations in one second then the frequency of sound wave is 200 vibrations per second. The SI unit of frequency is hertz.

Which among the following is true?a) Amplitude the distance travelled ...
Frequency is the number of vibrations made by a particle.
Frequency is a fundamental property of waves and is defined as the number of vibrations or cycles of a wave that occur in one second. It is usually denoted by the symbol 'f' and is measured in hertz (Hz).
Explanation:
Definition of frequency:
Frequency is defined as the number of complete cycles or vibrations of a wave that occur in one second. It represents the rate at which a wave oscillates or vibrates.
Example:
To better understand this concept, let's consider an example of a vibrating guitar string. When a guitar string is plucked, it starts to vibrate back and forth. The frequency of the string corresponds to the number of times it completes a full vibration in one second.
Relation to wave motion:
In wave motion, frequency is related to the speed of the wave and the wavelength. The formula to calculate frequency is:
Frequency = Speed of the wave / Wavelength
This formula shows that frequency is inversely proportional to wavelength. As the wavelength of a wave decreases, the frequency increases, and vice versa.
Importance of frequency:
Frequency is an important characteristic of waves and has various applications in different fields. In physics and engineering, frequency is used to analyze and understand wave behavior, such as in the study of sound waves and electromagnetic waves.
In communication systems, the frequency of waves is used to transmit and receive information. For example, radio waves have specific frequencies assigned to different stations, allowing us to tune in to the desired station.
Conclusion:
In summary, frequency is the number of vibrations or cycles of a wave that occur in one second. It is a fundamental property of waves and is measured in hertz. Understanding frequency is crucial in various fields and helps us analyze and utilize wave behavior.
