If you use a voltmeter to observe a voltage, it can only respond slowly, so if you want to observe a voltage that changes in fractions of a microsecond, you need a voltmeter that can respond at such speeds. It is called an oscilloscope.
Oscilloscope probes are used as part of an Oscilloscope. These are the pieces that connect to your circuit in which you would like to measure its sine waves.

The resistance of an ideal oscilloscope probe is infinity.
A standard oscilloscope is designed to measure voltage, you need a current probe for your oscilloscope to measure current.
In the name of Allah,the most Gracious,the most Merciful... The Oscilloscope has several advantages over a voltmeter, for example if you want to determine a signal parameters [ voltage values (max,peak-to-peak,rms,average...etc),frequency,offset...etc ] using measurement tools: 1- You can use the Oscilloscope whatever the signal frequency is, but you can't use the Avometer unless the signal frequency is 50 to 60 Hz. 2- The Oscilloscope shows you the shape (form) of the signal, while the Avometer doesn't. 3- You can determine the maximum value of the signal (max voltage) and peak-to-peak voltage when you observe the signal on an Oscilloscope,hence you can calculate the rms (root mean square) value, i.e. the effective value , the average value and the offset of signal form the time axis (the horizontal axis). While an Avometer can only give you the rms value.
please give me instruction to use an oscilloscope

An oscilloscope is sued to study A/C waveforms. Many engineers and techs use them.

yes
To measure using an oscilloscope, connect the oscilloscope probe to the signal source. Adjust the time and voltage scales on the oscilloscope to properly display the waveform. Use the cursors and measurements feature on the oscilloscope to measure parameters like frequency, amplitude, rise time, and pulse width.
How to use an oscilloscope is to complex for this Q & A site. Look for the model name and number on the piece of machinery. Go to the internet and look for the operational manual for the exact piece of equipment you have.

We can write oscilloscope as o'scope, or just call it a scope as a lot of electronics types do.
