What is Musical Sound   The sound producing pleasing effects on our ears are called Musical Sound.   2. Development of technology “blended education” (blended learning), which involves a combination of different methods of classroom and extracurricular learning. 3. Introduction of technology ” multimedia mobile learning ” (m-learning), which provides for the provision of educational…

What is Frequency in Physics   Frequency: It is the number of vibrations executed by an oscillating body in one second.   With synchronous learning, the student is involved in the learning system at the same time as the teacher. This type of learning includes direct, “live” learning, which consists in the interaction of the…

What is Time Period in Physics   Time Period (T): The time required to complete vibration is known as time period   Social networks are actively used by millions of people and have enormous educational potential. In addition to using social networks popular all over the world in teaching, higher education institutions can create their…

BA Poetry Notes   We are going to share with you the notes for different classes as mention above just for the help of our students, so that they can perform best in exams and in the near future, they can become good citizen of our society and take part in the development of our…

What is Vibration   One complete round trip of a simple harmonic motion is called vibration.   or   If a body in periodic motion moves to and fro over the same path, this motion is called Oscillation.   Buddying is a teaching method that involves students providing information and feedback to each other. Buddying…

Longitudinal and Transverse Waves   Longitudinal Waves:   In longitudinal waves, particles of the medium vibrate in the direction of the waves.   The portion of wave in which particles of medium are very close to each other is called compression.   Examples of longitudinal waves are sound wave and seismic waves.   Distance between…

Factors affect the Pitch of Sound   Pitch depends on following factors:   – Frequency of Vibrating Body: The greater the fundamental frequency, more shrill will be the sound.   – Relative Motion of Sound: If source and listener both are coming closer pitch will increase.   Problems related to the behavior of the student.…

What is Meant by Pitch   The sensation that a sound produces in o listener as a result of its frequency is known if as Pitch.   This is the property of sound by virtue of which we can distinguish between a shrill and grave sound.   Phlegmatic schoolchildren perform educational work, but do not…

Characteristics of Sound     The characteristic properties of sound by which we can distinguish between noise and music, shrill and grave sounds or sound of men and women are known as characteristics of sound. The properties of sound are given below:   Loudness:   Loudness is the magnitude of auditory sensation produce by sound.…

Propagation of Sound Waves   When a body vibrates in air, it produces longitudinal waves by compressions and rarefactions. These compressions and rarefactions are traveled by the particles of the medium and transferred into the next particles. Due to this transference, sound propagates in a medium.   Experiment: Suspend an electric bell in a jar…
