The frequency of an object is 200 Hz. If the velocity of sound in air ...
Given:
Frequency of the sound, f = 200 Hz
Velocity of sound in air, v = 340 m/s
To find:
Wavelength of the sound produced
Formula:
The relationship between frequency, wavelength, and velocity is given by the equation:
v = fλ
Where:
v = velocity of sound
f = frequency of sound
λ = wavelength of sound
Solution:
We are given the frequency of the sound as 200 Hz and the velocity of sound in air as 340 m/s. We can use the equation v = fλ to find the wavelength.
Substituting the given values into the equation, we have:
340 = 200 × λ
Simplifying the equation:
Dividing both sides of the equation by 200:
λ = 340/200
Calculating the value:
λ = 1.7 m
However, the answer options are given in centimeters. So, we need to convert the wavelength from meters to centimeters.
1 meter = 100 centimeters
λ = 1.7 × 100 cm
Simplifying the equation:
λ = 170 cm
Therefore, the wavelength of the sound produced is 170 cm, which matches with option C.
