Study Notes
Simple Harmonic Motion (SHM)
- SHM is characterized by oscillatory motion where acceleration is proportional to the displacement from the mean position, directed towards it.
- Examples of SHM include the motion of a mass on a spring, a pendulum, and a ball rolling in a bowl.
- The time period of a pendulum (time for one complete cycle) depends solely on its length and is independent of mass and amplitude.
Wave Characteristics
- Frequency is the number of cycles completed per second; it is the reciprocal of the time period.
- Amplitude refers to the maximum displacement from the mean position in SHM.
- A wave transfers energy without transferring matter from one location to another.
Types of Waves
- Mechanical waves require a medium for propagation.
- Electromagnetic waves can travel through a vacuum, not needing a medium.
- Transverse waves involve particle motion perpendicular to wave direction, while longitudinal waves see particle motion parallel to wave direction.
Wave Velocity Relation
- Wave velocity is calculated using the formula ( v = \frac{d}{t} ) (velocity = distance/time).
- For waves moving through a medium, if the time taken equals the wave’s time period ( T ), the distance covered is one wavelength ( \lambda ).
- The relationship between velocity ( v ), frequency ( f ), and wavelength ( \lambda ) is expressed as ( v = f\lambda ).
Example of Wave Motion
- A wave with a frequency of 4 Hz and wavelength of 0.4 m demonstrates that particles, like a piece of cork, move up and down in response to the passing wave, without traveling with it.
Wave Definition
- A wave is defined as a disturbance in a medium causing particles to vibrate around their mean position at equal time intervals. Thus, waves involve energy transfer while maintaining particle positions.
