Give 2 examples of things that are not matter and explain why they are not classifed as matter

Two examples of things that are not classified as matter are light and sound.
1. Light: Light is not considered matter because it does not have mass or occupy space. It is instead classified as electromagnetic radiation. Light consists of photons, which are massless particles that travel in waves. Although light can interact with matter, such as reflecting off surfaces or being absorbed by objects, it is not matter itself.
To understand why light is not matter, you can consider the definition of matter. Matter is anything that has mass and occupies space. In contrast, light has no mass, and its wave nature allows it to propagate through space without occupying a definite volume. Therefore, light does not meet the criteria to be classified as matter.
2. Sound: Sound is also not considered matter but rather a form of energy. Sound is produced by vibrations transmitted through a medium, usually air or some other material. When an object vibrates, it transfers energy to the surrounding particles, causing them to vibrate and transmit the sound wave.
Unlike matter, sound does not possess mass. It is a wave-like disturbance that travels through a medium, exerting energy but not occupying space or having a measurable mass. Sound can only be detected when it interacts with a receiver, such as our ears, and converted into electrical signals that our brain interprets as sound.
In summary, both light and sound are examples of things that are not classified as matter. Light is a form of electromagnetic radiation that lacks mass and does not occupy space, while sound is an energy wave that travels through a medium but does not possess mass.
