Ultrasound waves are those waves :

Ultrasonic waves are those waves which ……………

Sound waves are transverse waves.

Electromagnetic waves Electromagnetic waves are those waves in which there are sinusoidal variations of electric and magnetic fields at right angle to each other as well as right angle to the direction of propagation. The ratio of electric vector and magnetic vector gives the velocity of light and vecExxvecB gives the direction of propagation of electromagnetic wave. The electric and magnetic field of an electromagnetic wave are

Ultrasound waves compared to audible sound waves have _________ .

Why do ultrasound waves produce images of objects inside the body more effectively than audible sound waves do?

Electromagnetic waves Electromagnetic waves are those waves in which there are sinusoidal variations of electric and magnetic fields at right angle to each other as well as right angle to the direction of propagation. The ratio of electric vector and magnetic vector gives the velocity of light and vecExxvecB gives the direction of propagation of electromagnetic wave.
