Question

A sound has a higher pitch than a bell. Which quantity must also be higher in this sound than in the bell?(1 point) Responses frequency frequency wavelength wavelength speed speed amplitude

Answer 1

Which statement regarding sound traveling in air is correct? (1 point) Responses The frequency of a sound does not affect the speed at which it travels. The frequency of a sound does not affect the speed at which it travels. A loud sound travels faster than a quiet sound. A loud sound travels faster than a quiet sound. 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

Answer 2

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 decreases because molecules in the medium collide less 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 molecules in the medium collide more frequently. As temperature increases, the speed of sound increases because molecules in the medium collide more frequently. Changes in temperature have no effect on the speed of sound.
