Compare the velocity of sound waves in air and in steel. Explain the difference.

• The velocity of sound waves in air is much slower than in steel.

• The velocity of sound waves in air is the same as in steel.

• The velocity of sound waves in air is faster than in steel.

• The velocity of sound waves in air is not affected by the medium.

The equation to find the speed of a wave is...

• wave speed = frequency x wavelength

• wavelength = frequency x wavelength

• Wave speed = distance x time

• Wave speed = frequency x velocity
