An anode is an electrode, it can be a metal or another conductor. in an electrochemical cell that is polarized if an electric current flows into it. Electric current flows opposite to the direction of movement of electrons. In electrochemical processes, both galvanic cells (batteries) and electrolysis cells, anodes undergo oxidation.
In contrast to an Anode, a Cathode is an electrode pole in an electrochemical cell that is polarized if this pole is positively charged (so that an electric current will flow out of it, or the movement of electrons will enter this pole).
In galvanic cells or power plants (batteries), the anode is the negative pole. The electrode will release electrons towards the circuit and hence an electric current flows into this electrode and makes it an anode and negative.

<h3>What is long-sightedness?</h3>
Long-sightedness is an eye effect in which objects are not able to focus on the retina but behind the retina, therefore, near objects are not clearly seen except they are placed far away.
To correct long-sightedness, a suitable converging lens is used to bring the image to focus on the retina.
To construct a converging lens for Pak Dollah, the transparent plastic bottle is filled with water to serve as a converging lens and Pal Dollah will read through it.
Therefore, a converging lens made from a transparent plastic bottle filled with water is used to enable Pak Dollah read the newspaper.
