Physics P1 Part 1

1. Electromagnetic waves

   • 3 features
     • Wavelength-
     • Frequency-
       • Measured in Hertz(Hz) 1Hz=1 wavelength per second
     • amplitude-

2. Transverse and longitudinal waves

   • Transverse
     • Light
     • Water
     • S-waves
     • Ultravoilet
   • Longitudinal
     • Sound
     • P-waves
     • Ultrasound

3. Calculating wave-speed

   • Speed=frequency x wavelength
     • Speed= m/s
     • frequency=Hertz (Hz)
     • Wavelength= Metre

4. Digital and analogue

   • Digital-
   • Analogue-
