Emma, Arjun, and Hannah are studying linear algebra. They come across a concept called 'orthogonal transformation'. Can you help them understand what an orthogonal transformation is?

• It's a linear transformation that preserves the cross product of vectors, like when Emma rotates a 3D model in her computer graphics project.

• It's a non-linear transformation that preserves the dot product of vectors, like when Arjun adjusts the volume levels in his audio processing software.

• It's a linear transformation that changes the dot product of vectors, like when Hannah modifies the direction of a vector in her physics experiment.

• It's a linear transformation that preserves the dot product of vectors, like when Emma, Arjun, and Hannah rotate a figure in their geometry class without changing its shape.
