1. What are three types of waves? Long, Medium, Short Transverse, Longitudinal, Surface Transversal, Lengthwise, Surface Inner, Middle, Outer 2. Waves are classified according to how they _. look sound move appear 3. Waves that can travel through empty space are called _. mechanical waves electromagnetic waves sound waves vibration waves 4. Waves that require a medium through which to travel are called _. mechanical waves electromagnetic waves sonar waves vibration waves 5. Waves transmit _ from place to place. matter particles substance energy 6. Waves with a high frequency will have_ wavelength. long short medium no Use this image to answer questions 7-9. 7. The diagram above shows what type of wave? curly longitudinal typical transverse 8. In the diagram above, sections A, C, and E are examples of _. compressions rarefactions refractions collections 9. In the diagram above, sections B, D, and F are examples of _. compressions rarefactions refractions collections 10. In the diagram above, which wave has the largest amplitude? I II III They all have the same amplitude. 11. Another name for a longitudinal wave is _. depressional rarefactional mechanical compressional 12. Surface waves are _. transverse waves longitudinal waves a combination of transverse and longitudinal waves none of the above Use this diagram to answer questions 13-16. 13. The diagram above represents what type of wave? longitudinal compressional transverse sound 14. In the diagram above, the distance from B to F is _. wavelength amplitude frequency speed 15. In the diagram above, what part of the wave is D? amplitude compression crest trough 16. In the diagram above, the distance from the center line to B is _. amplitude frequency wavelength trough Fill in the Blank: Into each sentence below, select a term from the word bank that correctly completes the sentence.frequency refraction speed wavelength absorptionreflection medium diffraction transmission amplitude 17. A medium is a material through which waves can travel. It can be a solid, liquid, or gas.18. Frequency is the measure of how many waves pass a point in a certain amount of time.19. Transmission of waves occurs when waves pass through a given point or medium.20. Absorption occurs when the energy of a wave is not transferred through, or reflected by, the given medium.21. Amplitude is a measure of the distance from the resting point of a wave to a crest or trough.22. Refraction is the bending of waves caused by a change in their speed as they pass from one medium to another.23. Reflection is the bouncing back of a wave when it meets a surface or boundary that does not absorb the entire wave’s energy.24. Speed is a measure of the distance a wave travels in an amount of time.25. Wavelength is the measure of the distance from crest to crest or trough to trough of two consecutive waves.26. Diffraction is the bending of a wave as it goes around an object. 27. If an object looks blue, it reflects _ waves. blue red and yellow all but blue all 28. If no light is reflected, you see the color _. white black red blue 29. If all light is reflected, you see the color _. yellow black white blue 30. Sunburn and skin cancer are caused by _. infrared waves gamma rays microwaves ultraviolet waves The Eye Write the Correct answer: Use the word bank provided to correctly identify the structures of the eye.
