Study Notes
Wave Energy Transfer
- Waves transfer energy, but not matter.
- Both mechanical and electromagnetic waves transfer energy.
Wave Period Calculation
- Wave period (T) can be calculated using the equation: T = 1/f, (where f is frequency)
- The time period of a wave with a frequency of 5 Hz is 0.2 seconds.
- The time period of a wave with a frequency of 400 Hz is 0.0025 seconds.
Wave Velocity Calculation
- Wave velocity (v) can be calculated using the equation: v = fλ, (where f is frequency and λ is wavelength)
- Wave speed for a frequency of 50 Hz and wavelength of 6 meters is 300 meters/second.
- Wave speed for a frequency of 0.2 Hz and a wavelength of 25 meters is 5 meters/second.
Sound Waves
- Sound is a mechanical longitudinal wave.
- Sound is passed on by collisions between particles.
- Sound wave speed depends on the density of the particles.
- When sound moves between mediums, a change in speed causes a change in wavelength, but frequency remains constant.
- Wavelength is proportional to wave velocity when the frequency is constant.
