3. When two waves with the same amplitude and slightly differing frequencies are superposed (added), the result can be represented as a wave with oscillating amplitude. For sound waves, the amplitude is connected to the loudness, and the result is a sound rising and falling in loudness (this phenomenon is called "beatings"). Show this happens for the case 4 sin (2420mt) + 4 sin (2360mt)
