When two slightly different frequency waves superimpose _ is formed.

Explanation

When two sound waves of different frequency approach your ear, the alternating constructive and destructive interference causes the sound to be alternatively soft and loud - a phenomenon which is called "beating" or producing beats.When two slightly different frequency waves superimpose, beats are formed. Beats occur when two waves with slightly different frequencies interfere with each other. The resulting pattern consists of alternating regions of constructive and destructive interference, resulting in a periodic variation in the amplitude (loudness) of the combined wave.Stationary waves, also known as standing waves, are formed when two waves of the same frequency and amplitude traveling in opposite directions superimpose.Sound waves are longitudinal waves that result from the mechanical vibrations of particles in a medium, such as air or water.Beats occur when two waves with slightly different frequencies interfere with each other.Light waves are electromagnetic waves that consist of oscillating electric and magnetic fields.
