1. Week 22 1. John and his son Andrew were spending the day fishing off the pier over the ocean. Andrew began counting the waves as they passed under the end of the pier. He told his father that he repeatedly counted the same number of waves pass at each 10-second interval. What was Andrew actually measuring? a.Wavelength b.Frequency c.Speed d.amplitude SKIP A PAGE IN YOUR CRCT NOTEBOOK!

2. 2. How is amplitude related to energy? a.The larger the amplitude, the more energy a wave carries. b.The larger the amplitude, the less energy a wave carries. c.The shorter the amplitude, the more energy a wave carries. d.Amplitude is not related to energy.

3. 3. A wave has a low speed but a high frequency. What can be inferred about its wavelength? a.The distance of a wave will vibrate from its resting point. b.The wavelength will be very long. c.It depends on how fast the speed is. d.The wavelength will be short.

4. 4. What is the distance between two adjacent wave compressions? a.1 m/s b.1 wavelength c.1 Hz d.1 amplitude

5. 5. In which of the following materials are sound waves likely to travel most quickly? a.Liquid water b.Air at 4 degrees Celsius c.A piece of steel d.Air at 70 degrees Celsius

6. 6. Josh looks out a clear window and sees his friends skateboarding. What is happening to most of the light that strikes the window? a.It is absorbed. b.It is scattered. c.It is transmitted. d.It is reflected.

7. 7. Which object is MOST LIKELY to absorb light energy and convert it to thermal energy? a.A mirror b.A sheet of white paper c.A black asphalt driveway d.A light-colored shingled roof

8. 8. What causes sound waves? a.Vibrations b.A medium c.A low pitch d.amplitude

9. 9. What does pitch describe? a.How high or low a sound seems. b.How many waves pass a point in a given time period c.The length of a wave d.The amplitude of a wave

10. 10. Allie noticed that a stick she placed in a pond appeared to be broken at the point entering the water. What caused this? a.Refraction of light waves from the water. b.Light waves interfering with one another. c.Reflection of light waves from the water. d.Reflection of light waves bouncing off the bottom of the pond.
