Answer:
Therefore, the speed of sound in air, with a frequency of 1120 Hz and a wavelength of 30 cm, is approximately 336 meters per second.
Step-by-step explanation:
To find the speed of sound in air, we can use the formula:
speed = frequency × wavelength
Given:
Frequency (f) = 1120 Hz
Wavelength (λ) = 30 cm
First, we need to convert the wavelength to meters since the speed of sound is commonly expressed in meters per second.
1 meter = 100 centimeters
Wavelength in meters (λ) = 30 cm ÷ 100 = 0.3 meters
Now we can substitute the values into the formula:
speed = frequency × wavelength
= 1120 Hz × 0.3 meters
Calculating the value:
speed = 336 meters per second
