### 1.3

1. 1. Science Starter : February 9, 2012 <ul><li>The speed of a waves equals its wavelength times its amplitude . </li></ul><ul><li>Wavelength measures the distance from one wave crest to the next. </li></ul><ul><li>The number of wavelengths passing a point in a given time is a wave’s amplitude . </li></ul><ul><li>As the frequency of a wave increase, its wavelength increases . </li></ul>Write out the statement. If it is true leave it alone, if it is false change it to make it true . BE SURE TO WRITE THE DATE
2. 2. Waves Behave in Predictable Ways Pages 24-28 (section C)
3. 3. Waves interact with materials <ul><li>As you watch the ripple effect in the water, observe how the wave reacts. </li></ul>
4. 4. Reflection <ul><li>The bouncing back of a wave after it hits the barrier </li></ul><ul><ul><li>Example: the waves hitting the side of the container </li></ul></ul>
5. 5. Refraction <ul><li>Refraction- the bending of a wave as it enters a new medium at an angle other than 90 degrees </li></ul><ul><ul><li>Example: a straw or pencil that appears broken in a glass </li></ul></ul>
6. 6. Diffraction <ul><li>Diffraction- the spreading out of waves through an opening or around the edge of an obstacle </li></ul>
7. 7. Interference <ul><li>Interference- the meeting and combining of waves </li></ul>
8. 8. Constructive Interference <ul><li>Two waves add together to make a larger wave </li></ul>
9. 9. Destructive Interference <ul><li>Two waves that cancel each other out </li></ul>
