Question

Use the following information to answer the next question.

In ultrasound technology, sound waves with a frequency of 3.02 x 10° Hz
and a wavelength of 5.13 x 10-4 m pass through the body. Reflected waves
are analyzed by a computer to produce an image.
The speed of the sound waves passing through the body is
A.
B.
C.
D.
1.70 x 10-10 m/s
1.55 x 103 m/s
3.00 x 108 m/s
5.89 x 10 m/s

Answer 1

B. 1.55 × 10³ m/s

Step-by-step explanation:

f = 3.02 x 10^6 Hz

wavelength = 5.13 x 10^-4 m

v = ?

v = f*lamda

v = 3.02 x 10^6 × 5.13 x 10^-4

v = 1.55 × 10³ m/s
