This document defines and provides units for key terms used in the study of transverse waves: wavelength is the distance between crests or troughs and is represented by λ; amplitude is the height of crests or depth of troughs and is represented by a; frequency is the number of waves passing in one cycle and is represented by f; and wave velocity is the distance travelled by the wave in one second and is represented by v. It also presents the relationship that connects these terms: wave velocity equals wavelength multiplied by frequency, or V=fλ.
3. WAVELENGTH,λ
WAVELENTH IS THE DISTANCE BETWEEN
ADJACENT CREST OR TROUGH.
IT IS REPRESENTED BY THE GREEK LETTER
LAMBDA,λ
ITS UNIT IS METRE OR CENTIMETRE.
4. AMPLITUDE,a
It is the height of the crest
or depth of the trough.
It is represented by the
letter ‘a’.
Its unit is metre or
centimetre.
5. FREQUENCY,f
It is the number of waves passing in the wave in
one cycle.
It is represented by the letter f.
Its unit is Hertz(Hz)
6. WAVEVELOCITY,V
It is the distance travelled by the
wave in one second.
It is represented by the letter v.
Its unit is m/s.
