Waves Unit Study Guide

  1. Waves are rythmic disturbances that transfer _____________. Electromagnetic (light) waves behave ________________ than mechanical (sound) waves.
  2. Label and describe the wave below.
  3. Label and describe the wave below.
  4. Complete the chart below to compare transverse and longitudinal waves.
  5. Use the above chart to SUMMARIZE transverse waves. TRANSVERSE WAVES carry energy. Transverse waves have crests. Transverse (light) waves DO NOT need a medium to transfer energy. Transverse waves carry light energy.
  6. Use the above chart to SUMMARIZE longitudinal waves. Longitudinal waves carry energy. Longitudinal waves have frequency which is the number of waves lengths that pass through a given area in a specific time. Longitudinal waves have rarefactions and compressions. Longitudinal waves MUST HAVE A MEDIUM to transfer energy.
  1. Compare and contrast electromagnetic and sound Waves.
  2. Use the above chart to SUMMARIZE electromagnetic waves. Electromagnetic waves have wavelengths. The longer the wavelength the lower the frequency. They carry energy. Electromagnetic waves carry LIGHT energy.
  3. Use the above chart to SUMMARIZE sound waves. Sound waves are longitudinal waves. Sound waves have wavelengths. The longer the wavelength, the lower the frequency, the lower the pitch. Sound waves MUST have a MEDIUM to travel. Sound waves carry energy. Sound waves are mechanical waves that carry sound.
  4. Complete the chart below to compare and contrast sound and light wave interactions.
  1. Draw and explain what happens to light waves when they pass through a CONVEX lens. A convex lens is an outward curved transparent lens. It is thicker in the middle. The light rays that pass through the convex lens converge or come together.
  2. How do CONVEX lenses affect how images are seen? (Virtual or Real) Give examples of technological applications that use CONVEX lenses. Depending on the placement of the object and the focal point it will produce a REAL image or a virtual (larger) image. Convex lenses are used to magnify objects. They are used in telescopes, binoculars, microscopes, magnifying glasses, and glasses for corrective farsighted vision.
  3. Draw and explain what happens to light waves when they pass through a CONCAVE lens. A concave lens is an inward curved transparent lens. It is thinner in the middle. The light rays that pass through diverge, or spread apart.
  4. How do CONCAVE lenses affect how images are seen? (Virtual or Real) Give examples of technological applications that use CONCAVE lenses. Concave lenses produce virtual (smaller) images. Concave lenses are used in glasses for corrective nearsighted vision.
  5. Explain how light is transmitted through the following materials: opaque, translucent, and transparent. Opaque materials do not allow light to pass through (they reflect or absorb all of the light); translucent materials allow some light to pass through, but it is scattered and blurry; transparent materials allow light to pass through clearly.
  6. Use the above diagram to explain the Law of Reflection? All waves obey the law the reflection. The law of reflection states that the angle of incidence equals the angle of reflection. The arrow labeled reflected ray represents the wave that bounces off. The incoming wave or incident ray represents the wave moving toward the surface at an angle. The plane mirror is perpendicular to the incoming wave.
