← ScienceWhich outcome arises via Einstein's equivalence principle when an observer within a freely falling elevator shines a laser horizontally?
A)The beam bends downward slightly.✓
B)The beam remains perfectly horizontal.
C)The beam splits into two beams.
D)The beam increases in frequency.
💡 Explanation
The laser beam bends slightly downward because, via the equivalence principle, gravity is indistinguishable from acceleration; therefore the light path curves as the elevator accelerates 'upward' relative to the beam, rather than remaining straight as it would in an inertial frame.
