Indicate the possible effects of ultrasound on the substance: electromagnetic; thermal; mechanical; chemical; electrical; magnetic;

Ultrasound can have several effects on substances, including:<br /><br />1. Thermal effect: Ultrasound can cause heating of the substance due to the vibration of molecules. This is known as the thermal effect of ultrasound.<br /><br />2. Mechanical effect: Ultrasound can cause mechanical vibrations in the substance, leading to changes in its physical properties.<br /><br />3. Chemical effect: Ultrasound can induce chemical reactions in the substance by increasing the kinetic energy of the molecules.<br /><br />4. Electrical effect: Ultrasound can generate electrical currents in certain substances, such as piezoelectric materials.<br /><br />However, ultrasound does not have a direct effect on electromagnetic, magnetic, or electrical properties of a substance.
