A speaker suspended high in the air, away from other objects, emits one spherical wave with total energy 5 J. Assume the waves travel at the speed of sound in air: 343 m/s. Draw the wave 2 seconds and 5 seconds after it was emitted. Label the total energy at each of these times. Label the energy per unit area for each of these times. I would like to know how should I approach this problem when it comes to sound waves and how do I apply total energy in this problem?

Interference of Light

The word "constructive" signifies addition in interference. Constructive interference occurs when the path of the waves that start from the slit differs by 1 entire wavelength or in the intervals of the same. Hence, the waves that are presented on the screen are in phase (crest to crest/trough to trough). The waves interfering constructively forms bright fringes on the screen.
