Physics 165/164 Homework Assignment #4 Due, Friday 29 February 2008 at the beginning of class. Read sections 2.1 and 2.5 of Handout #4 (on the particle theory of light). Read sections 3.1, 3.2, 3.3, and 3.5 of Handout #5 (on the wave theory of light). Solve Problems: 1. In a typical introductory physics class, the velocity v of a particle is deFned as v = Δ x Δ t = x f - x i t f - t i where the particle is at position x i at time t i and (later) at position x f at time t f ( t f >t i ). (a) If a particle begins at the origin ( x = 0 when t = 0) and is later observed at x =24 . 0 m when t =3 . 0 s, what is the velocity of the particle? (b) If another object is located at x =24 . 0 m when t =3 . 0 s and is later observed at x =6

These radio waves travel at the speed of light. What is their wavelength? 3. What are (a) the amplitude, (b) the frequency in hertz, (c) the wavelength, and (d) the speed of a water wave whose displacement is given by y ( x, t ) = 0 . 5 sin(0 . 6 x-2 . 7 t ) , where x and y are in meters and t is in seconds?
