Redshift (Sound): The decrease in frequency (and increase in wavelength) of a sound wave as the source moves away from the observer. Blueshift (Sound): The increase in frequency (and decrease in wavelength) of a sound wave as the source moves toward the observer.

(See Figure \PageIndex3.) Later in this text we will look at the efficiency of energy transfers in greater detail and learn why they happen the way that they do.

Snell's Law: Describes the relationship between the angles of incidence and refraction, stating that the ratio of the sines of these angles is equal to the ratio of the indices of refraction of the two media.
