Diagonal Matrices, Upper and Lower Triangular Matrices
{ De nition: An upper triangular matrix is a square matrix in which all entries below the main diagonal are zero (only nonzero entries are found above the main diagonal - in the upper triangle). A lower triangular matrix is a square matrix in which all entries above the main diagonal are zero

2.2 The Michelson-Morley Experiment
faculty.etsu.eduJun 24, 2019 · Example (Exercise 2.2.2). Suppose L1 is the length of arm #1 and L2 is the length of arm#2. The speed of a photon (relative to the source) on the trip “over” to the mirror is c − v and so takes a time of L1/(c − v). On the return trip, the photon has speed of c +v and so takes a time of L1/(c +v). Therefore the round trip time is t1 ...
