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

What is this phenomenon called?
REFRACTION

4. 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

6. 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 .

7. 6. What is the difference between CONSTRUCTIVE INTERFERENCE and DESTRUCTIVE INTERFERENCE?
