  1. Waves CRCT CRCT lesson 22 &23

  2. 1. John and his son Andrew were spending the day fishing off the pier over the ocean. Andrew begancounting 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? • Wavelength • Frequency • Speed • Amplitude

  3. 2. How is amplitude related to energy? • The larger the amplitude, the more energy a wave carries • The larger the amplitude. The less energy a wave carries • The shorter the amplitude, the more energy a wave carries • Amplitude is not relate to energy

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

  5. 4. What is the distance btw two adjacent wave compressions? • 1 m/s • 1 WL • 1Hz • 1 amplitude

  6. What happens when a light wave strikes a mirror? • The wave refracts from the mirror B. The mirror absorbs the wave C. The mirror transmits the wave D. The eave reflects off the mirror

  7. As Alex looks through a clear window, what occurs as light hits the window? • Most of the light is scattered • Most of the light is absorbed C. Most of the light is reflected D. Most of the light is transmitted

  8. What happens to a wave as it passes from one medium to another? • The wave refracts • The wave absorbs the medium • The wave transmits the medium • The wave is reflected

  9. What occurs when a wave moves from one medium into another and the wave is refracted ? • The wave spreads out • The wave changes direction • The wave is scattered • The wave changes frequency

  10. Lesson 21

  11. How are waves classified as either longitudinal or transverse? • By size, color, shape, strenght and intensity • By the amount of vibration through the air • By how they move and by the medium through which they travel • By the amount of EM they contian

  12. 2. What do waves transfer? • Matter • Energy • Water • air

  13. 3. What will happen to the boat? • It will sink • It will move up and down • It will not move • It will travel straight to the other end of the tub

  14. 4. What will happen to the surface of the water? • Waves will move out from the disturbance • The waver will remain calm • A wave will move from the surface to the bottom of the tub • The water level will go down

  15. Lesson 24

  16. 1. What is the first structure of the eye through which light passes? • Cornea • Pupil • Lens • Retina

  17. 2. How does the lens of the eyes focus light on the retina? • It cause light rays entering the eye to spread apart. • It bends light rays entering the eye in a way that brings them together. • It brings light rays entering the eye together and then without being refracted. • It forces light rays to travel straight through the eye without being refracted.

  18. 3. Which of the following BEST describes the images formed on the retina of the eye? • It is smaller than the object being viewed, but it is right-side up. • The image is upside down compared to the actual object being viewed • The image is much larger than the actual object viewed. • If the object is close , the image formed is enlarged and right side up.
