Ultrasound reflected from an oncoming bloodstream that is moving at a 30 cm/s is mixed with the original frequency of 2.5 MHz to produce beats. What is the beat frequency in Hz? (Velocity of sound in blood = 1540 m/s.)

Ultrasound is a type of sound wave that has a frequency higher than the upper limit of human hearing, which is around 20,000 Hz. It is used in many medical and industrial applications, such as imaging, surgery, and cleaning.
The frequency of ultrasound is measured in hertz (Hz), which is a unit of frequency equal to one cycle per second. This means that the frequency of ultrasound is the number of sound waves that pass through a point in one second.
The beat frequency of ultrasound is determined by the difference in frequency between the two sound waves that are interacting. It is the difference between the transmitter frequency and the receiver frequency.
Yes, the beat frequency of ultrasound can be changed by adjusting the frequency of either the transmitter or the receiver. This is often done in medical ultrasound imaging to produce different images of the same area.
The typical beat frequency of medical ultrasound ranges from 1 to 15 MHz (million hertz), depending on the type of imaging and the depth of the tissue being imaged. Higher frequencies are used for superficial imaging, while lower frequencies are used for deeper imaging.
