Question

Joanna wants to determine the speed of sound in xenon. When she plays a tone with a frequency of 440 Hz, the resulting sound wave has a wavelength of 40.4 cm.
a 1090 m/s
b 178 m/s
c 92 m/s
d 343 m/s

Answer 1

The speed of the sound in the xenon is 178 m/s. And the right option is b 178 m/s

What is speed?

Speed can be defined as the ratio of the total distance traveled by a body to the total time taken.

To calculate the speed of the sound in the xenon, we use the formula below.

Formula:

• v = λf............. Equation 1

Where:

• v = Speed of the sound in xenon
• f = Frequency
• λ = Wavelength.

From the question,

Given:

• f = 440 Hz
• λ = 40.4 cm = 0.404 m

Substitute the values above into equation 1

• v = 440(0.404)
• v = 177.76 m/s.
• v ≈ 178 m/s

Hence, The speed of the sound in the xenon is 178 m/s. And the right option is b 178 m/s
