Saturation divers who spend days or weeks under water often breathe a mixture of helium and oxygen. One side effect of this gas mixture is that it makes the divers' voices higher-pitched. What is the cause of this increase in pitch?
Ultraviolet, X-rays, gamma rays, and sound waves travel faster in the helium-oxygen mixture, resulting in a higher frequency for the same wavelength.
Sound waves travel slower in the helium-oxygen mixture, resulting in a higher frequency for the same wavelength.
The helium-oxygen mixture decreases the amplitude of the waves, which increases their frequency.
The helium-oxygen mixture increases the amplitude of the waves, which increases their frequency.

A) The bending of waves around obstacles
B) The change in direction of waves when they pass from one medium to another
C) The spreading out of waves when they pass through a narrow opening
D) The bouncing back of waves when they hit a surface
