Answer 1

Amplitude, in physics, the maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position. It is equal to one-half the length of the vibration path.

Velocity is a measure of how fast something moves in a particular direction. ... For instance, if an object moves east at 9 metres per second (9m/s), we would say that its velocity is 9 m/s to the east.

Wavelength, distance between corresponding points of two consecutive waves. ... Wavelength is usually denoted by the Greek letter lambda (λ); it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): λ = v/f.

Frequency, in physics, the number of waves that pass a fixed point in unit time; also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.

Wave number, a unit of frequency in atomic, molecular, and nuclear spectroscopy equal to the true frequency divided by the speed of light and thus equal to the number of waves in a unit distance.

Answer 2

$\huge{\boxed{\sf{ANSWER-}}}$

$\huge{\boxed{\sf{AMPLITUDE(A)-}}}$

=) IT IS HEIGHT OF CREST OR DEPT OF TROUGH.✔✔

□UNIT OF AMPLITUDE IS UNIT OF DISTANCE:[cm,m,so on]

$\huge{\boxed{\sf{VELOCITY(V)-}}}$

=) THE LINEAR DISTANCE TRAVELLED BY WAVE PER SECOND IS CALLED VELOCITY OF WAVES.✔✔

□UNIT OF VELOCITY:[cm/sec,m/sec,km/hr]

$\huge{\boxed{\sf{WAVELENGTH(λ)-}}}$

=)THIS LINEAR DISTANCE BETWEEN ANY TWO CONSECUTIVE CREST OR TROUGH IS KNOWN AS WAVELENGTH OF WAVES.✔✔

□UNIT OF WAVELENGTH:[cm,m,mm,angstron(A°)]

$\huge{\boxed{\sf{FREQUENCY-}}}$

=) THE NUMBER OF CYCLES PASSING TROUGH A POINT PER SECOND IS CALLED FREQUENCY OF WAVES.✔✔

□UNIT OF FREQUENCY:$\frac{cycle}{sec}$,HERTZ.

$\huge{\boxed{\sf{WAVE\:NUMBER-}}}$

=)IT IS RECIPROCAL OF WAVELENGTH OR THE NUMBER OF WAVES IN ONE UNIT OF LENGTH IS CALLED WAVE NUMBERS.✔✔

$\huge{\boxed{\sf{Y=\frac{1}{λ}}}}$

□UNIT OF Y:${cm}^{-1}$
