A wave with a shorter wavelength is always faster than one with a longer wavelength.
A wave with a shorter wavelength is always faster than one with a longer wavelength.
As the wavelength increases, the frequency also increases.
As the wavelength increases, the frequency also increases.
A loud sound travels faster than a quiet sound.

None of the statements is correct. The speed of sound in air is mainly determined by the temperature and humidity of the air, and is not affected by the frequency or amplitude of the sound wave. Wavelength and frequency are inversely proportional, so as wavelength increases, frequency decreases, and vice versa. The loudness of a sound is not related to its speed of propagation.
Which statement about the effect of temperature on the speed of sound is correct?(1 point)
Responses
As temperature increases, the speed of sound increases because the medium becomes denser.
As temperature increases, the speed of sound increases because the medium becomes denser.
As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.
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.
