Chapter 1 Section Reviews Sound and Light: Waves and Properties of Waves
1.1 Where do waves get their energy? Waves get their energy from a source of vibration or disturbance.
1.2 Name three types of waves. Give an example of each. Transverse – wave on a rope Longitudinal – “compression” wave on a slinky. Surface – wave on the surface of water
1.3 When a wave passes a ship at sea, how does the wave affect the ship? The wave causes the ship to move up and down. Because we are dealing with a surface wave the ship also moves in a circular motion. (a combination of longitudinal and transverse waves)
1.4 The vibrations produced by a jackhammer are used to break up pavement. What type of waves do you think the jackhammer produces in the ground? Transverse – waves along the surface of the pavement perpendicular to the force of the jackhammer. Longitudinal – “compression” waves that travel into the ground in the same direction of the force of the jackhammer.
2.1 List the four basic properties of waves. Describe each property. Amplitude– distance from rest position to crest or trough. wavelength– distance from crest to crest or trough to trough. Frequency – number of waves that pass a given point each second. Speed – distance traveled in a given time.
2.3 Can two waves have the same wavelength but different amplitudes? Explain. Yes! Two waves can have the same frequency but different amounts of energy.
2.4 When you increase the tension on a wire the speed of the waves on it increases, but the wavelength stays constant. What happens to the frequency of the waves as the tension on the wire is increased? Use the frequency formula to see what happens. Substitute numbers for the speed and wavelength and find its affect on the frequency.
