Answer 2

The ultrasound waves can penetrate into matter to a large extent because they have B. very high frequency

Explanation:

• Sound wave with higher frequency is called as ultrasound waves.
• Properties of ultrasound is similar to sound wave but it cannot be heard by human ears.
• The hearing range of human ears is 20 Hz to 20 kHz where ultrasound waves is from 20 kHz to many gigahertz.
• Ultrasound waves are used in sonogram, to determine the distance of an object, accelerating chemical process and in nondestructive testing.
