To help students to acquire knowledge on Mechanical Vibrations, Waves, and Fundamentals of Acoustics and Optics. The student must be able to: identify / characterize different types of oscillatory motion of systems with one degree of freedom, compute natural frequencies and resonance frequencies. Concerning wave motion the students must be able to determine the fundamental characteristics of the waves: amplitude, wavelength, period/frequency and speed; calculate wave functions. The students must acquire knowledge on the fundamental concepts of acoustic; they must calculate the intensity of a sound, they must be familiar wuth the decibel scale, and understand the Doppler effect. Finally, they must understand the phenomena of reflection and refraction of light, and improve their knowledge on the optical properties of materials.
