Answer:
The minimum thickness of the Lucite plate is 0.670 μm.
Explanation:
Given that,
Wavelength = 650.0 nm
Index of refraction = 1.485
We need to calculate the minimum thickness of the Lucite plate
Using formula of thickness
Where, n = Index of refraction
= wavelength
Put the value into the formula
Hence, The minimum thickness of the Lucite plate is 0.670 μm.
By definition, the power is given by:
Where,
F: Force
d: distance traveled
t: time
The power units is watts.
Substituting values we have:
Making the corresponding calculations we have:
Answer:
he uses 63 watts of power:
