Answer: 0.04metres
Explanation:
The wavelength of a wave is the distance covered by the wave after one complete cycle. It is measured in metres, and represented by the symbol λ
Recall that Velocity (V) = Frequency F x wavelength λ
V = F λ
Make λ the subject formula
λ = V / F
In this case Frequency = 0.4 kHz
Convert kilohertz to hertz by multiplying 0.4 by 1000 i.e (0.4 x 1000Hz) = 400Hz
Velocity of wave = 16 m/s
So, λ = V / F
λ = 16 m/s / 400Hz
λ = 0.04metres
Thus, the wavelength of a wave is 0.04metres
Earth's orbit and climate change
Answer:
The frequency of the sound.Hope this helps btw
Explanation:
You would need to know how fast the sound waves go through the air.
Answer:
Gravity.
Explanation:
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.
