Acoating of film n=1.33 on glass slabs (n=1.6) is 8.3×10e−5 cm thick. if white light is incident normally, which visible wavelengths are missing in the reflected light?

the missing wavelengths would be those that give length of

Explanation:

Data:

Let the coating of the film be n = 1.33 on glass

The refractive index = 1.6

Thickness of the slab = 8.3 × 10⁻⁵ cm

Therefore, the angles are all determined from the normal

This gives:

The relationship, known as Snell's law, can be used to evaluate the missing angles in the wavelength region.

a.) travels faster in solids because the particles are closer together.

air is a gas water is a liquid

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
