- HW 2) The beam from a small laboratory laser typically has an intensity of about 1.0 x 10-3 W/m2. Assuming that the beam is composed of plane waves, calculate the amplitudes of the electric and magnetic fields in the beam. 31 co Dr AQEEL SAUM 1/10/20221. Assuming the angular frequency of the source is 1000 rad/s, determine the phase shift between V(t) and I(t) in degrees.2. What must be the operating frequency of the source for V(t) and I(t) to be in phase? Use Hertz.3. Determine the maximum magnitude of I(t) as the frequency of the source gets varied.PROBLEM4: The mass m, stiffness k, and natural frequency , of an undamped SDF system are unknown. These properties are to be determined by harmonic excitation tests. At an excitation frequency of 4 Hz, the response tends to increase without bound (i.e., a resonant condition). Next, a mass Aw=2 kg is attached to the mass m and the resonance test is repeated. This time resonance occurs at f=3 Hz. Determine the mass and the stiffness of the system.
