Answer:
the thickness of the mica is 6.64μm
Explanation:
By definition we know that the phase between two light waves that are traveling on different materials (in this case also two) is given by the equation

Where
L = Thickness
n = Index of refraction of each material

Our values are given as

Replacing our values at the previous equation we have


the thickness of the mica is 6.64μm
That would happen at any place where they don't have to
fall through air or anything else.
Examples:
-- on the moon
-- on an asteroid
-- on a comet
-- on Mercury
-- on Earth, in a vacuum chamber with all the air pumped out of it
When a boy throws a ball and accidentally breaks a window, the momentum of the ball and all the pieces of glass taken together after the collision is THE SAME as the momentum of the ball before the collision
