Question

An ultrasonic transmitter is producing waves at a frequency of 5.000 MHz (recall that Mega 10*). If the speed of the ultrasonic signal in biological tissue is 1540 m/s, what is the wavelength (in mm) associated with this ultrasonic wave? Express your answer using the correct number of significant digits. 1. Wavelength mm 2. A stationary source is emitting sound of frequency 1200.0 Hz. What frequency is perceived by an observer moving toward the source at a speed of 34.00 m/s. Assume the speed of sound is 340.0 m/s. Perceived frequency Lightning strikes a tree on top of Pinnacle Mountain which happens to be 2.00 miles from your location. Recall that 1.00 mi is equivalent to 1609 m. You see the flash of light almost immediately because the speed of light is very great. Assume it is a typical August day in Arkansas, temperature of 95.0 °F. 3. Recall TeF) = (9/5) T(°C) + 32-(9/5) (T(K)-273) + 32 (You will need to convert temperature to Determine the speed of sound in air at 95 absolute in K and then use the temperature dependence relationship on the information page.) a) F. Speed of sound at 95 °F = Now determine the time it takes for the sound of the thunder associated with the lighting strike to reach your cars. b) Time to reach your ears- (Uf you do this correctly you will verify the rule of thumb that says it takes between 4 and 5 seconds for sound to travel I mile in air or 3 seconds to travel 1 km)

Explanation / Answer

1.

From the relation of wave speed, v= wavelength *frequency

1540= 5*106* wavelength

Wavelength= 1540/(5*106)= 0.308 mm
