Express your answer in terms of some or all of the variables f and L. Use the numeric value given for n in the introduction.
T = ___________ s
Answer:

Step-by-step explanation:
Given:
Thickness og glass = L
Index of refraction n=1.5
Frequency = f

λ(air) 
λ(glass) = λ(air) / n
= 
= 
= 
V(glass) = fλ(glass)


8 inches. 3/4 of 8 feet is 6 feet leaving two left over, one third of that is 8 inches.
Equation = 12 - -24 = ?
After keep, change, flip: 12 + 24 = ?
