(Get Ready, Get Ready, Get, Ready!) QUIZ (Get Ready, Get Ready, Get, Ready!) AGAIN!!!!

The angle between the incoming wave and the imaginary perpendicular line is called _ANGLE OF INCIDENCE_____ .

2. When a wave moves from one medium into another medium at an angle, it changes speed as it enters the second medium, which causes it to bend. What is this phenomenon called? REFRACTION

3. What is occurring when a wave passes a barrier or passes through a hole in a barrier, such that it bends and spreads out? DIFFRACTION

4. The reflection diagram with ALL PARTS LABELED!

5. What does the Law of Reflection state? THE LAW OF REFLECTION STATES THAT THE INCIDENT RAY, THE REFLECTED RAY, AND THE NORMAL TO THE SURFACE OF THE MIRROR ALL LIE IN THE SAME PLANE. FURTHERMORE, THE ANGLE OF REFLECTION IS EQUAL TO THE ANGLE OF INCIDENCE .

6. What is the difference between CONSTRUCTIVE INTERFERENCE and DESTRUCTIVE INTERFERENCE? CONSTRUCTIVE INTERFERENCE WILL MAKE A SOUND LOUDER WHILE DESTRUCTIVE INTERFERENCE WILL MAKE A SOUND QUIETER.
