Morphology
space-reflection + symmetry
The phrase decomposes straightforwardly into 'space-reflection' (reflecting spatial coordinates) + 'symmetry' (invariance), so the meaning — invariance under spatial reflection — is directly derivable from the constituents. It is a technical term but compositionally transparent, so a B1 learner who knows 'space', 'reflection' and 'symmetry' can infer the general idea even if they lack physics background.
Etymology
Space-reflection symmetry comes from the image of a 'mirror': if you flip space left and right (a space-reflection) and things look the same, that is symmetry. So when the rules of physics would be 'unchanged' by this flip, we say they have space-reflection symmetry.
