Unit 4: Waves
Energy may be transferred by matter or by waves. Waves transfer energy without transferring mass. Most of the information scientists gather about the universe is derived by detecting and analyzing waves. This process has been enhanced through the use of digital analysis. Types of waves include mechanical and electromagnetic. All waves have the same characteristics and exhibit certain behaviors, subject to the constraints of conservation of energy.

I can understand the wave is a periodic disturbance in a medium and the energy can be transferred by wave by observing the behavior of waves. I can determine the characteristics of waves by the wave length, wave frequency, and wave amplitude. I also can analyze the wave frequency change in studying the relative motion of stars and light refraction phenomenon by applying the Doppler’s effect and Snell’s law respectively.
