I'm looking for a real-world scenario that illustrates the concept of injective. Can someone provide me with a practical example of how injective functions work in our daily lives?

One example is the relationship between a student's name and their roll number in a class. Each student has a unique name and a corresponding roll number.

This mapping is injective because no two students can have the same roll number, ensuring that each roll number corresponds to exactly one student.

Another example is the relationship between a person and their shadow, assuming a single light source. Each person casts a unique shadow, and no two people can cast the same shadow under the same lighting conditions.

This scenario also demonstrates an injective function, as each person's shadow is distinct and can be traced back to only one person.

Here are several practical illustrations of injective functions.
