Ratio is 1.10 for part 1.
1. Determine the ratio for the speed of light in ethyl alcohol (n=1.36) to the speed of light in benzene (n=1.50).
2. If light travels for 3.0ns in ethyl alcohol, how much further will it travel in this material than it would in benzene? answer will be in terms of speed of light in benzene, Vbenzene.
here is my work for part 2 but i don't think its right,
for part 2 knowing Ve/Vb = 1.10
d=Vet
Vc=(1.10)Vb
d=Vet
Ve=(1.10)Vb
de=(1.1)Vbt
de=(3.0x10^9s)Vb
d=1.10Vb x 3.0x10^-3
d=1.10 x 3x10^-3 Vb
Vb(3x10^-9) = d
