Chapter 11 Waves

Chapter 11.1 Notes Wave is a disturbance that transmits energy through matter and space. Medium is the matter through which a wave travels. Mechanical wave requires a medium to travel through. (sound) Electromagnetic wave does NOT require a medium to travel through. (light)

Vibrations are produced by waves.

Transverse wave cause the particles of the medium to vibrate perpendicularly to the direction the wave travels.

Longitudinal wave causes the particles of the medium to vibrate parallel to the direction the wave travels.

Chapter 11.2 Notes Crest is the highest point of a wave. Trough the lowest point of a wave. Amplitude is the greatest distance that particles in a medium move from their normal position when a wave passes. Wavelength the distance between any two successive identical parts of a wave.

Period the time required for one full wavelength to pass a certain point. Frequency the number of vibrations that occur in 1 second time interval. Wave speed the speed at which a wave passes through a medium.

Electromagnetic spectrum is the full range of light at frequencies that we cannot see directly. Visible light this is the range of light our eyes can detect.

Formulas Frequency = Speed = Wave speed= frequency x wavelength 1 period Distance Time Wavelength period

The Doppler Effect the change in frequency of a wave resulting from the motion of the source or observer.

Chapter 11.3 Notes Reflection- the bouncing back of a wave as it meets a surface or boundary. Diffraction- the bending of a wave as it passes an edge or an opening. Refraction- the bending of a waves as they pass from one medium to another.

Interference the combination of two or more waves that exist in the same place at the same time. 2 Types of Interference 1.Constructive interference any interference in which waves combine so that the resulting wave is bigger than the original waves. 2.Destructive interference any interference in which waves combine so that the resulting wave is smaller than the largest of the original waves.

Standing wave- a wave form caused by interference that appears not to move along the medium and that shows some regions of no vibration (Nodes) and other regions of maximum vibration (antinodes).
