WebThe Total internal reflection is responsible for all of the phenomina given above. Option 4. All of are true is …. Total internal reflection allows light to travel in a curved path inside an optic fiber. o occurs when light strikes an interface at greater than the critical angle. accounts for the brilliance of cut diamonds. All of these are true. WebNot really. Light just follows a curved path in the curvature of space-time produced by a massive object (a consequence of gravity). But, gravity itself doesn't slow down light. Because, we've just corrected these gravitational waves (a century ago) to not to be instantaneous, but travel exactly at c as a consequence of SR, which declares speed ...

WebDec 22, 2024 · The notion of a straight line being the shortest path applies only in Euclidean geometries. For a general curved manifold, which we deal with in GR, we instead talk about geodesics.Light does bend, in the sense that it follows curved geodesics, though in these geometries it doesn't make sense to talk about straight lines any more: the notion is … WebNov 22, 2024 · Light also travels along geodesics (called null geodesics), and so paths of light are also curved by gravitational force, despite the light not having any mass.
