A sound wave moves through air and hits a solid steel block. Part of the sound is reflected by the steel, and part passes through the steel. How do the speed and wavelength of the sound in steel compare with the speed and wavelength of the sound in air?
- Aspeed less than in air; wavelength less than in air
- Bspeed less than in air; wavelength greater than in air
- Cspeed greater than in air; wavelength less than in air
- Dspeed greater than in air; wavelength greater than in air
