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)
