No. Diffraction is not a wave; it is something that HAPPENS to waves; to all sorts of waves.
Yes.
diffract
Yes even sound waves diffract
Wavelength.
Wavelength.
You can reflect it, absorb it or even diffract it (a bit).
No, a sound wave is a compressional wave.
the wave length stays the same length, it'll just diffract fron the air to the water and vice versa.
No. A sound wave is a pressure wave.
electromagnetic wave is not a sound wave
An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.
It propagates by the to and fro motion of air particles along the direction of wave propagation. Compressions (regions of high air density and pressure) and rarefactions (regions of low air density and pressure) are set-up in the process. Its propagation is aided due to the fact that sound can diffract through very large angles. This is due to the large wavelength of the sound waves.
yes a sound wave is a Compressional wave
