What is the minimum (non-zero) thickness ttt of the film that produces a strong reflection for green light with a wavelength of 500 nmnm

200 nm.

Explanation:

The minimum thickness can be found using the following equation:

Where:

t: is the thickness =?

m: is the order of interference = 1 (since it is minimum)

n: is the refractive index = 1.25

λ: is the wavelength = 500 nm

Therefore, the minimum thickness is 200 nm.

I hope it helps you!

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
