  2. How do you add two waves with different amplitudes?
  3. Can two waves with different frequencies be added together?

What happens when you add two sine waves with different frequencies?

When two sinusoids of different frequencies are added together the result is another sinusoid modulated by a sinusoid. The math equation is actually clearer. The amplitudes have to be the same though.

How do you add two waves with different amplitudes?

When two waves occupy the same point, superposition occurs. Superposition results in adding the two waves together. Constructive interference is when two waves superimpose and the resulting wave has a higher amplitude than the previous waves.

Can two waves with different frequencies be added together?

This wave fluctuates in amplitude, or beats, with a frequency called the beat frequency. We can determine the beat frequency by adding two waves together mathematically. ... Adding two waves that have different frequencies but identical amplitudes produces a resultant x = x1 + x2.
