Compute the wavelength in air of ultrasound with a frequency of 50 kHz if the speed of sound is 344 m/s.

v = f*lambda

where v is the speed of sound, f is the frequency, and lambda is the wavelength

Thanks, but I don't understand. Am I going to muliply 50*344?

To compute the wavelength of ultrasound, we can use the equation:

Wavelength = Speed of Sound / Frequency

Let's substitute the given values into the equation:

Wavelength = 344 m/s / 50 kHz

However, we need to convert the frequency from kHz to Hz since the speed of sound is given in meters per second. 1 kHz is equal to 1000 Hz.

Wavelength = 344 m/s / (50,000 Hz / 1 kHz)

Wavelength = 344 m/s / 50,000 Hz * 1 kHz

Wavelength = 344 m/s / 50,000,000 Hz

Now, let's compute the wavelength:

Wavelength = 0.00688 meters or 6.88 mm

Therefore, the wavelength of ultrasound with a frequency of 50 kHz in air is approximately 6.88 mm.

To compute the wavelength, we can use the formula:

Wavelength = Speed of Sound / Frequency

First, we need to convert the frequency from kHz to Hz:

50 kHz = 50,000 Hz

Now, we can substitute the values into the formula:

Wavelength = 344 m/s / 50,000 Hz

Calculating this, we find:

Wavelength = 0.00688 meters (or 6.88 mm)

Therefore, the wavelength in air of the ultrasound with a frequency of 50 kHz is 6.88 mm.
