Does the responsibility for drug education and prevention lie primarily with the family, the schools, the church, the police, or with the state and federal governments? How would you rank order their responsibility? Justify your order.

A light ray strikes the perfectly smooth boundary between two different materials. The index of refraction of the material before the boundary is lower than that of the material after the boundary. On the basis of this information, the light ray will be

a. partially transmitted in a direction deviating more from the normal and partially reflected.

b. partially transmitted in a direction deviating less from the normal and partially reflected.

c. partially transmitted exactly in the same direction and partially reflected.

d. totally transmitted exactly in the original direction, without any reflection.

e. totally reflected in the first material, without any forward transmission.

A certain material has an index of refraction of 5/4. That means that in this material, as compared to a vacuum, light

a. travels at the same speed but has (4/5) of the frequency it would have in a vacuum.

b. travels with a speed (5/4) c and the frequency is the same it would be in a vacuum.

c. travels at the same speed but has (5/4) of the frequency it would have in a vacuum.

d. travels with a speed (4/5) c and has (4/5) the frequency it would have in a vacuum.

e. travels with a speed (4/5) c and the frequency is the same it would be in a vacuum.

Consider the following wave equation for u(t, x) with boundary and initial conditions defined for 0 ≤ x ≤ 2 and t ≥ 0.

∂ 2u ∂t2 = 0.01 ∂ 2u ∂x2 (0 ≤ x ≤ 2, t ≥ 0) (1)

∂u ∂x(t, 0) = 0 and ∂u ∂x(t, 2) = 0 (2)

u(0, x) = f(x) = x if 0 ≤ x ≤ 1 1 if 1 ≤ x ≤ 2.

(a) Compute the coefficients a0, a1, a2, . . . of the Fourier cosine series of f(x) in the interval 0 ≤ x ≤ 2. For your calculation, recall that sin(πn) = 0 for all integers n.

(b) Find all the possible values of λ, µ ≥ 0 such that the function v(t, x) = cos(λx) cos(µt) solves the wave equation (1) and the boundary condition (2).

(c) Use the superposition principle, the Fourier series coefficeints a0, a1, . . . from part (a) and the functions v(t, x) from part (b) to write down an expression for the solution u(t, x) of the boundary and initial condition problem (1)–(3).
