TRUE OR FALSE PLEASE SOLVE ILL FOLLOW AND THANK AND MARK AS BRAINLIST
BUT DONT MAKE UP ​

Answer 1

Explanation:

1.Infrasonic waves are used by doctors to produce images of body organs

• False:- ultrasonic waves are used by doctors to produce images of body organs

2. Sound can travel in all three states of

matter

• Ture

3.Sound waves travel through compressions.

• True

4.A shrill sound has lower frequency than a dull sound.

• False:-A loud sound has a higher amplitude and more energy. Pitch is basically the frequency of the sound that the human ear understands. A sound having a higher frequency is said to have a high pitch and lower frequency sounds have low pitch. So, a shrill sound has a high pitch and a dull sound has a low pitch.

5.Loudness of sound depends on its wavelength.

• False:- The loudness of a sound depends on the amplitude of vibration producing the sound.

6.We can hear a sound of frequency 20,250 Hz.

• False:- This is called audible range of frequency. So, human can hear sound of frequency 100 Hz.

hope it helps you!!

if yes then help others, this will be my gift

no need of thanks and brainliest
