1. Discuss the circular drumhead and the 2D wave equation is applicable. 2.solve the 2D wave equation on the drumhead, subject the boundary condition that the solution dont blow up at the origin and show that solutions go to zero on the edge of the drumhead. 3. show that the above boundary conditions give you standing wave patterns. 4. find pictures or better make plots of some of the standing wave patterns on the drumhead and discuss the solutions compare and contrast them with sines and cosines in rectangular case.

CONTENT REVIEW: TRUE OR FALSE Determine whether each statement is true or false. Then on a separate sheet of paper, write "true" if it is true. If it is false, change the underlined word or words to make the statement true. 1. A medium transfers wave matter. 2. The crest of a wave is the maximum dis- placement upward. 3. Molecules spread out in rarefaction. 4. A transverse wave is a series of compres- sions and rarefactions. 5. The distance between two consecutive crests is one amplitude. 6. Frequency is measured in hertz. 7. The incoming wave is the standing wave. 8. The bending of waves due to a change in speed is called reflection. 9. When two waves combine to subtract from each other, destructive interference occurs. 10. Constructive interference and destructive interference producing stationary nodes and antinodes is called a diffraction wave.

1 In this lab, you will need to be able to describe how multiple waves interact with each other. 1) This does not add too much mathematical complexity to the wave equation (Eq 2), and 2) it allows us to develop a closer approximation of real-life situations as well (e.g. interacting ripple patterns in a pond, music, atomic physics, etc.). Here you will explore the superposition of two waves, y₁ and y2, where Y₁ × Y₂ ((πx Y2 Which of the following expressions accurately describes how these two distinct waves will combine? We call this interaction the principle of superposition. - = sin ((T2 − 27t) × (5 +27t))=sin( + n²xt - 4π²₁²) (2²22² Y1 X Y2 = sin (7 − 27t) x sin (2 +27t) Y₁ = sin(x - 2πt) and πX Y₁ + y₂ = sin (TX 2πt + ₂ + 2πt) 2 Y₁ + y2 = sin(x − 2πt) + sin(+2πt) +2πt) = sin (³) 2 Y2 = sin(+2πt) -D-O
