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. ... Waves are generated by vibrating sources, their amplitude being proportional to the amplitude of the source.
.
2- The period of a wave is the time for a particle on a medium to make one complete vibrational cycle. Period, being a time, is measured in units of time such as seconds, hours, days or years. The period of orbit for the Earth around the Sun is approximately 365 days; it takes 365 days for the Earth to complete a cycle.
.
3 - Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. Frequency is measured in hertz which is equal to one event per second.
.
4 - Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave. ... Wavelength is inversely proportional to frequency. This means the longer the wavelength, lower the frequency. In the same manner, shorter the wavelength, higher will be the frequency
.
5- Wave velocity, distance traversed by a periodic, or cyclic, motion per unit time (in any direction). ... The velocity of a wave is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity
