Wavelength is the least distance between any two

λ Wavelength (λ) is the least distance between any two points in phase

360 o = 2Π radians Q. A mains transformer vibrates the floor at 50 Hz. What is the time for a complete cycle?

Wave speed equation speed = distance time

Wave speed equation

λ B Wavelength (λ) is the least distance between any two points in phase d A Phase difference between particles at A and B = 2 Π d radians λ Phase difference is the fraction of a cycle between two particles measured in radians or degrees.

λ B Wavelength (λ) is the least distance between any two points in phase d A Phase difference between particles at A and B = 2 Π d radians λ 360 o = Phase difference is the fraction of a cycle between two particles measured in radians or degrees. 2Π radians
