The wave encounters some corner or a small opening. The wave bends and fan The wave encounters some change in medium. The wave moves through the n at which it hit the surface. Two waves move towards each other and the crest of each wave overlaps, crea individual wave. The wave encounters some obstacle or change in medium. The wave bounces an angle equal to the one at which it hit the surface. Study the image of a wave moving from air to liquid.

The frequency is ½ second, and the period is 2 Hz. The period is ½ second and the frequency is ½ Hz. The period is ½ second, and the frequency is 2 Hz. The period is 2 s, and the frequency is 2 Hz. Study the images showing interaction of two waves and the result. © 2016 FlipSwitch © 2016 FlipSwitch What type of behavior is modeled by the images? The images show two waves overlapping destructively, because destructive inte and cancel each other. These waves partially cancel each other. The images show two waves overlapping constructively because constructive in and result in a smaller or larger wave. These waves partially build each other up The images show two waves overlapping constructively because constructive in overlap and result in a smaller or larger wave.

A region of rarefaction overlaps wit correctly describes the behavior of sound waves when they overlap as described? Destructive interference; the sound becomes louder because the amplitude incr Destructive interference; the sound becomes quieter because the amplitude de Constructive interference; the sound becomes louder because the amplitude inc Constructive interference; the amplitude increases but the volume remains the s A sound wave with a frequency of 400 Hz is moving through a solid object.

Which choice most accurately descr rock? Visible light is absorbed by both the rock and the plastic, making both objects w allowing visible light through the rock and the plastic. Visible light is absorbed by the rock and the plastic making both objects warmer visible light through the plastic. None of the light hitting the rock is reemitted. Visible light is absorbed by the rock, making it warmer. Light is also absorbed by either object is reemitted. Visible light is absorbed by both the rock and the plastic, making both objects w allowing visible light through the rock. None of the light hitting the plastic is reem Study the scenario. A beam of light hits a sheet of metal. If it has enough energy, electrons break free from Which choice correctly describes the behavior of light in this situation? In this situation, light behaves as a particle colliding with another object. This is increases the energy carried by each electron but does not increase the numbe In this case, light acts like a wave because it requires the total energy of a wave light beam doesn’t releases any more electrons but it does increase the energy In this case, light acts like a wave because it requires the total energy of a wave light beam releases more electrons and increases the energy carried by each e In this situation, light behaves as a particle colliding with another object.
