Abeam of light is traveling in air and strikes a material. the angles of incidence and refraction are 63.0° and 47.0° respectively. obtain the speed of light in the material.

Speedd of the light in the medium is

Explanation:

According to Snell's law we have

Since incidence medium is air thus we have

Applying values we get

Now we know that speed of light in any medium is given by

where is the refractive index of the medium and 'c' is the speed of light in vacuum

Thus upon applying values we get

the following is queen elizabeth’s purposes:

- to encourage the parliament that the technique of picking successors to the seat based merely on birthright needs to be reviewed.

- (not) to convince the parliament that her kid should not be measured as a likely choice for heir to the english power.

- to persuade the parliament that merely since she has a child does not assure that the kid will be a capable leader.

- to sway the parliament how shattering it could be if they proceeded discourteously concerning her or her child.
