If is positive and is zero, what is the sign of Justify your answer using the last two ΔV ΔU Q? equations? Section X: For problems, 44 47, use the equations – If is constant, how does change if quadruples? v f λ is to 3x108 m/s. What is the value of if equals 2.25 x 108 m/s? c n v If is greater than is greater than, less than, or to Justify your answer using the third n2 n1, θ1 θ2? equation?
If ΔV is positive and ΔU is zero, what is the sign of Q? Justify your answer using the last two equations? Section X: For problems, 44 – 47, use the equations If v is constant, how does f change if λ quadruples? c is to 3x108 m/s. What is the value of n if v equals 2.25 x 108 m/s? If n2 is greater than n1, is θ1 greater than, less than, or to θ2? Justify your answer using the third equation?
