Physics · Alternating Current
Which of the following statements is FALSE for a complex alternating wave that is periodic and has identical positive and negative half-cycles?
- 1The harmonic with the lowest frequency is called the fundamental harmonic.
- 2The two halves of the complex wave are identical when only even harmonics (2nd, 4th, 6th etc.) are present.✓
- 3The two halves of the complex wave are identical in shape when only odd harmonics (3rd, 5th, 7th etc.) are present.
- 4The frequency of the complex wave is the same as that of the first harmonic of that wave.
Correct answer
The two halves of the complex wave are identical when only even harmonics (2nd, 4th, 6th etc.) are present.
