Answer:
123.18 nm
Explanation:
Given:
- Refractive index of the glass=1.5
- Index of magnesium fluoride=1.38
- Wavelength of the light =680 nm
Let t be the thickness of the film. The relation between the wavelength of light in film and thickness of the film in order to have no reflection is given by
Now According to question we have
where n is the refractive index of the film.
Now thickness t is given by
Hence the thickness of the film is calculated in order to have no reflection.

Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.
i hope this answers your question. it wasnt very clear what the question was though

Answer:
this description is valid for mediadle displacement, bone is an acceptable description
Explanation:
The description of a person's position must be done with a position vector. These vectors must have magnitude, a given direction and a starting point.
In the description this has a starting point corner NO of pine and 675.
Each displacement occurs with respect to the previous one, indicating the magnitude of the displacement and its direction.
After analyzing this description is valid for mediadle displacement, bone is an acceptable description
