Which statement regarding sound traveling in air is correct?

Question

(1 point)
The frequency of a sound does O not affect the speed at which it travels.
A wave with a shorter wavelength is always faster than one with a longer wavelength.
A loud sound travels faster than a quiet sound.
As the wavelength increases, the frequency also increases.

Answer 1

The frequency of a sound does not affect the speed at which it travels.

Answer 2

Which statement about the effect of temperature on the speed of sound is correct? (1 point)
Changes in temperature have O no effect on the speed of sound.
As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.
As temperature increases, the speed of sound decreases because molecules in the medium collide less frequently.
As temperature increases, the speed of sound increases because the medium becomes denser.

Answer 3

As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.
