frequency and wavelength
wavelength and wave speed
amplitude and wavelength ***
amplitude and frequency

3. Soundproof rooms take advantage of which property of waves? (1 point)absorption
regular reflection
refraction ***
diffuse reflection
Are my answers right?

Answer 2

1. C) amplitude (2 m) and wavelength (35 m)
The second one I don't know I hope I Helped

Answer 3

it's okay thanks for the first one though and ill keep making sure ,


6. The difference between the speed of sound in air at 0° C and the speed of sound in air at 20° C is that (1 point)

cooler air molecules move more slowly and respond less readily to the energy of a sound wave.
cooler air molecules move more quickly and respond less readily to the energy of a sound wave.
cooler air molecules do not move and respond less readily to the energy of a sound wave.
cooler air molecules move more randomly and respond less readily to the energy of a sound wave. ***
