The concepts of orthogonal and orthonormal vectors are pretty easy to understand. These concepts are applied when you are performing dot product on two vectors. Hence, when you apply dot product, you will either get orthogonal vectors are orthonormal vectors.
Two vectors are orthogonal or perpendicular if their dot product is zero. This means that both vectors are perpendicular to each other because the component becomes zero when the angle between both vectors is and when is zero that means the dot product of both vectors is zero.
Not perpendicular which means both vectors are also not orthogonal.
Two vectors are orthonormal if:
1. Their dot product is zero.
2.The two vectors are unit vectors.
One of the most frequently asked questions is the difference between orthonormal and orthogonal vectors. Orthonormal vectors are the same as orthogonal vectors but with one more condition and that is both vectors should be unit vectors. If both vectors are not unit vectors that means you are dealing with orthogonal vectors, not orthonormal vectors.
