Looks ok, except that it violates the usual rules of significant digits. Since the given frequency and speed have only one such the answer should be given as ##3\times 10^2##Hz. On the other hand, the question setter might not have intended that.nao113 said:
Doppler Frequency Shift for Ultrasonic Waves is a phenomenon where the frequency of an ultrasonic wave changes when the source of the wave and the observer are in relative motion. This shift in frequency is caused by the change in distance between the source and observer, and is commonly observed in medical ultrasound imaging and Doppler radar systems.
The formula for calculating Doppler Frequency Shift for Ultrasonic Waves is: Δf = 2f0(v/c)cosθ, where Δf is the frequency shift, f0 is the original frequency of the wave, v is the relative velocity between the source and observer, c is the speed of sound, and θ is the angle between the direction of motion and the direction of the wave. This formula takes into account the effects of both the motion of the source and the observer.
The Doppler Frequency Shift for Ultrasonic Waves can be affected by several factors, including the velocity of the source and observer, the angle between the direction of motion and the direction of the wave, and the speed of sound in the medium. Additionally, the frequency of the wave itself can also impact the amount of frequency shift observed.
Doppler Frequency Shift is an important aspect of medical ultrasound imaging as it allows for the detection of movement and flow within the body. By measuring the frequency shift of the reflected ultrasonic waves, doctors can gather information about the direction and speed of blood flow, as well as detect any abnormalities or blockages.
Doppler Frequency Shift is utilized in Doppler radar systems to measure the speed and direction of moving objects, such as weather patterns or aircraft. By analyzing the frequency shift of the reflected signals, the radar system can determine the velocity of the object and track its movement over time.
