The phenomenon of "broken mirror but difficult to round" referred to the fact that when an object was subjected to an external force, its distortion would produce stress, causing cracks or marks on the surface of the object, or even destroying the original complete shape. This phenomenon usually occurs when the surface of an object is squeezed or stretched, such as a broken mirror or a stretched plastic pipe. In the process of dispersion, when a substance enters another substance through a hole or channel, it will spread along the channel to the surface of the other substance. This phenomenon is called the law of dispersion, which states that the concentration of matter decreases in inverse proportion to the square of distance. However, when there was an interface between two objects, the concentration of the substance might suddenly change at the interface, causing the phenomenon of "broken mirror and difficult circle" to occur. This is because when a substance enters another substance, it will have a local high concentration phenomenon at the interface. Such a high concentration might attract other substances to spread in that direction, causing the original shape to be unable to be restored. In addition, when a substance enters another substance, it may undergo a chemical reaction that causes the concentration of the substance to change, resulting in the phenomenon of "broken mirror and difficult to circle".

Alright, here are some basic physics problems in junior high school and the corresponding physicists and their corresponding inventions: What is Newton's first law? A: Newton's first law states that any object will remain stationary or move in a straight line at a constant speed without the effect of an external force. Physicist: Isaac Newton The discoverer of Newton's first law was the British scientist Isaac Newton. 2 What is electricity? A: Electricity is a physical phenomenon that can be expressed as the interaction between electric charges. Physicist: Isaac Hendrikse [Description: Coulomb's law states that the interaction force between two electric charges is inverse proportional to the square of the distance between them.] 3 What is a magnetic field? A: Magnetic fields are generated by electric currents and can be expressed as the surrounding magnetic field around magnetic objects. Physicist: John James Clerk Maxwell [Description: Maxwell's equations describe the laws of motion of the electromagnetic field, including Ampere's law and the Farady's law of electromagnetic induction.] What is the reflection of light? A: When light shines on the surface of an object, part of the light will be reflected back, and the other part will penetrate the object and enter the air. Physicist: Aristotle [Creation: The law of light reflection proposed by aristotle.] What is electromagnetic wave? A: Electromagnetic waves are a kind of physical medium that will not be weakened during transmission. They can be expressed as radio waves, microwave, infrared rays, visible light, and so on. Physics: Maxwell [Description: Maxwell's equations describe the law of electromagnetic wave transmission.] 6 What is heat? A: Heat is a physical phenomenon that can be expressed as a change in the temperature of an object.

The saying 'broken mirror is hard to mend' is a metaphor for two broken relationships or objects that cannot be restored to their original state or reconciled. The meaning of this idiom is to emphasize that it is difficult to restore a relationship or object that has lost its balance or broken. The following methods could be used to make a broken mirror reunite: 1. Re-establish trust: If the relationship is broken for some reason before the broken mirror is re-established, then re-establishing trust is the key to restoring the relationship. This required both parties to be honest with each other and trust each other to eliminate previous misunderstandings and contradictions. 2. Repair the broken surface: If the broken mirror only has some broken pieces or surface damage, you can use some measures to repair it. For example, he could reapply a protective layer or use other materials to fill in the damaged parts. 3. Find common ground: Reuniting the broken mirror requires both parties to find common ground and reestablish contact. They could find new common ground through communication, cooperation, or solving problems together to repair their relationship. Physics simple question: Suppose a cup was smashed to the ground and some fragments were produced. If the shards were sharp and hard, they could stab fingers or other parts of the body. If the shards were soft, they might be deformed or stuck together, unable to pierce the fingers or other parts of the body. Therefore, the appropriate shape of the fragments should be soft and elastic so that they can be deformed or stuck together to avoid damage.

The light phenomenon mind map was as follows: ``` | | V | | E | | H F | | | | G | | C D C | ``` These are the three basic functions of light: reflection, refraction, and interference. Next was the phenomenon of light refraction: ``` | | V | | E | | H F | | | | G | | C D C | ``` This was the new light produced by the refraction of light. The direction and length of these light rays would change when observed from different angles. Next was the phenomenon of light reflection: ``` | | V | | E | | H F | | | | G | | C D C | ``` This is the reflection of light on a flat mirror or other reflective device. The direction and angle of the reflected light remain the same, but the path of the light has changed. Next was the interference phenomenon: ``` | | V | | E | | H F | | | | G | | C D C | ``` This was an interference phenomenon caused by the collision of two or more beams of light. In the interference, the paths of light would intertwine with each other to form interference fringes. The above are the three basic functions of light and the phenomenon of light interference.
