Back

Ultrasound is inaudible to humans because it operates at frequencies higher than the upper limit of human hearing, which is about 20 kHz.

Front

What is the primary use of ultrasound in medicine?

Back

Ultrasound is primarily used in medical imaging to visualize internal organs, tissues, and blood flow.

Front

What is the difference between frequency and amplitude?

Back

Frequency refers to the number of waves that pass a point in a given time, while amplitude refers to the height of the wave, indicating its energy or loudness.

Front

What is an example of a longitudinal wave?

Back

Sound waves in air are a common example of longitudinal waves.

Front

What is the relationship between frequency and pitch?

Back

Higher frequency sound waves correspond to higher pitch, while lower frequency sound waves correspond to lower pitch.

Front

What technology uses sonar?

Back

Sonar technology is used in submarines, fishing boats, and oceanographic research to locate objects underwater.

Front

What is echolocation?

Back

Echolocation is a biological sonar used by some animals, like bats and dolphins, to navigate and locate prey by emitting sound waves and listening for echoes.
