Question

Calculate the speed of sound on a day when a (1500 Hz) frequency has a wavelength of (0.221 m).

a) (335 m/s)
b) (330 m/s)
c) (325 m/s)
d) (320 m/s)

Answer 1

To find the speed of sound with a given frequency and wavelength, we multiply the two values together. In this case, 1500 Hz times 0.221 meters equals 331.5 m/s, which rounds to the nearest option, 330 m/s (option b).

Step-by-step explanation:

To calculate the speed of sound on a day when a frequency of 1500 Hz has a wavelength of 0.221 m, we can use the formula for wave speed, which is the product of frequency (f) and wavelength (λ). The formula is given by:

Speed of sound (v) = frequency (f) × wavelength (λ)

Substituting the given values:

v = 1500 Hz × 0.221 m

v = 331.5 m/s

Since we need to match the answer to the closest option in the multiple-choice questions, the closest value to our calculated speed is 330 m/s, which is option (b).
