Physics CH 8 powerpoint & notes

A device or structure that converts one form of energy into another is:

• pzt crystals

• transducer

• conductor

• matching layer

Electrical energy is converted to acoustic energy during:

• reception

• transmission

• scanning

• offtime

Reflected acoustic energy is converted to electrical energy during:

• reception

• scanning

• ontime

Electrical energy from the system is converted into sound during:

• reception

• transmission

• offtime

Reflected sound is converted into electricity during:

• reception

• transmission

• scanning

• ontime

PZT crystals are made of:

• barium titanate

• lead titanate

When pressure is applied to certain materials, they deform and produce an electrical voltage. This is the:

• reverse piezoelectric effect

• piezoelectric effect

• Huygen's Law

• Bernoulli's Principle

When voltage is applied to certain materials, it causes them to vibrate, producing sound waves. This is the:
