momentum is the product of mass and velocity
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.
