No, the glowing of a light bulb is a reversible change because it can be turned off by disconnecting the power source. The light bulb will stop glowing once the electrical current is interrupted.
Reversible: the light goes on, producing illumination; it goes off and it's as dark as it was. Irreversible: light causes a plant to grow which is not immediately reversed when the light is turned off
Cutting down a tree. shredding of paper as well as same of the irreversible change
Rain is a natural phenomena and is not reversible.
Irreversible chemical change.
Burning of a cracker is an irreversible change. Once the cracker is burnt, it undergoes a chemical reaction that cannot be easily reversed to its original form.
The glowing of an electric bulb is a physical change. This is because the light produced is a result of energy being converted into electromagnetic radiation, without any change in the chemical composition of the bulb's components.
The act of lighting a bulb is an irreversible change because the light and heat produced cannot easily be reversed to return the bulb to its original state. Once the electrical current passes through and illuminates the filament, the light is emitted permanently.

It is a physical change. When you supply electricity, the electrons jump to higher energy state. When they come back to their level, it emits energy which falls in the visible region of light. The atoms of the filament (Tungsten) are not going through any change, that changes their chemical properties. Tungsten, still remains tungsten!

irreversible change is called a physical change.
The glowing of the metal wire in an incandescent light bulb when switched on is a physical change, specifically a thermal change, as it involves the wire heating up and emitting light due to increased temperature. When the light is switched off, the wire cools down and stops glowing, indicating a reversible process. However, the wire itself does not undergo any chemical change during this process.
Burning something is irreversible.
