Physical ultrasonics is a mature field and in this review some branches of the subject are discussed. After a brief introduction, various ultrasonic transducers like piezoelectric, ceramic, capacitive, electromagnetic and optical methods for generation of ultrasonic waves have been discussed. Some linear and non-linear ultrasonic phenomena are then summarized. In the case of non-linear phenomena, parametric arrays, acoustic cavitation, sonoluminescence and sonochemistry have been presented. A discussion of surface acoustic waves and devices, optical storage cell, acoustooptic effects and underwater acoustics is then given. Finally some special topics such as, acoustic emission, acoustic microscopy, sound amplification by stimulated emission of radiation, medical diagnosis and ultrasonic lithotripsy are discussed briefly
