All sine waves both sound and electromagnetic.
Yes.
The greater the amplitude, the higher the crests and lower the troughs.
Wave length.
destructive interference
The distance between the either the crests or troughs of one cycle in a wave.
Yes.
No
The greater the amplitude, the higher the crests and lower the troughs.
Wavelength is the measure of distance between adjacent crests or troughs.
Wave length.
destructive interference
That's the wave's frequency.
The distance between the either the crests or troughs of one cycle in a wave.
Principle of Super position of waves.
Two.
Two.
That's called the wavelength.
