can you hear that my task

so today we are gonna read the book about
                                               can you hear that ?
what is  amplitude mean ? 

what is  amplitude mean ? amplitude are expressed either as instantaneous values or mostly as peak values and if you listen to anything that means it is so loud and like a animal.Also animal they can make a sound and also if the cow is angry because if we still there milk  they starting to make a sound and it so loud.And it good if you listen and you can remember what your friend talk to and ask to you so that the mean of the amplitude

what is  a frequency  mean ?
frequency is the number of complete cycles per second in alternating current direction. The standard unit of frequency is the hertz,Frequency is how often an event repeats itself over a set amount of time. In physics, the frequency of a wave is the number of wave crests that pass a point in one second (A wave crest is the peak of the wave). Hertz (symbol Hz) is the unit of frequency.

what is wavelength mean ?
Wavelength and frequency. Light is measured by its wavelength (in nano-meters) or frequency (in Hertz). One wavelength. equals the distance between two successive wave crests or troughs. Lesson Summary
Waves are described and measured by five wave parameters: the period, the frequency, the amplitude, the wavelength, and the speed.Wavelength is the distance between two identical adjacent points in a wave. It is typically measured between two easily identifiable points, such as two adjacent crests or troughs in a waveform.
