USING OF SOUND-Part 1

​What are some applications of sound waves?

An echo is a copied sound that comes back to the source of the sound after reflecting or bouncing off a surface.

​

Echo

Echolocation is a method used by different animals to navigate , communication, and finding food.

Echolocation

Multiple Choice

Which sound wave-object interaction is used by animals in echolocation?

• Reflection

• Refraction

Application of sound to people

-is a technology that uses high frequency sound waves.

• Frequency is the number of wavelengths that pass a fixed point in one second

​

ULTRASOUND

Multiple Choice

Which one has the low Frequency?

Multiple Choice

Which one has the high Frequency?

Ultrasound imaging is a technology that uses high frequency sound waves to create images.
Ultrasound imaging depends on sound wave-object .

• The machine generates sound waves that are reflected by parts of the body.

• The reflection of sound waves creates echoes.

• The echoes are received and processed into images.

​

ULTRASOUND IMAGING

​Ultrasound is used to make sure that a fetus in its mother’s womb is developing properly.

Multiple Choice

In ultrasound technology, which type of sound wave-object interaction creates echoes that are processed to form images?

• reflection

• refraction

Ultrasound is used to make sure that a fetus in its mother’s womb is developing properly.

​Ultrasound technology can help diagnose diseases and injuries.

• Ultrasound can detect kidney stones.

• Ultrasound can reveal injuries in animals.

ULTRASOUND TECHNOLOGY

Ultrasound Technology in Treating Diseases

Ultrasound technology is used to diseases.

Sound waves are absorbed by:

• kidney stones, until they are enough to exit the body.

• cancer cells, which are warmed up and destroyed.

Multiple Choice

Which type of sound wave-object interaction breaks down kidney stones and destroys cancer cells?

• absorption

• reflection

• diffraction

Ultrasound Technology for Cleaning

• It also can clean large pieces of machinery.

Cleaning lenses

• It cleans small items, such as lenses, jewelry, watches, and surgical tools.

Multiple Choice

Which of these statements accurately describe uses of ultrasound technology?

• It can be used to clean large items like machinery and small items like jewelry

• It increases the production time of everyday materials.

• It cannot be used in the presence of liquids like water.
