Which one has more dangerous effect for health ...ultrasound or infrasound.? and why...

Sound waves travel through the air and enter our ears. The waves cause our eardrums to vibrate, which then sends signals to our brain that we interpret as sound. Higher frequency sound waves can cause our eardrums to vibrate more rapidly, producing a higher pitched sound, while lower frequency waves produce lower pitched sounds.
Yes, sound waves can have a physical effect on objects. When sound waves travel through a medium, such as air or water, they cause the molecules in that medium to vibrate. This vibration can cause objects to move or even break if the sound waves are strong enough.
Sound waves can be used in medical treatments in a process called ultrasonography. High frequency sound waves are directed into the body and the echoes are used to create images of internal structures. This technique is commonly used in pregnancy to monitor the development of the fetus and in other medical procedures, such as diagnosing heart problems or detecting tumors.
No, sound waves can only travel through materials that have molecules that can vibrate, such as air, water, and solids. However, the speed and intensity of the sound waves may vary depending on the type of material. For example, sound waves travel faster through solids than through air.
Sound waves and light waves are both forms of energy that travel in waves, but they have different properties. Sound waves are mechanical waves that require a medium to travel through, while light waves are electromagnetic waves that can travel through a vacuum. Additionally, sound waves have a lower frequency and longer wavelength compared to light waves, which have a higher frequency and shorter wavelength.
