What is the index of refraction of a medium if the critical angle is 40.0°, assuming the second medium is air?

Explanation:

The refractive index of a medium (n) is defined as angle of refraction per angle of incidence. When the angle of incidence in water reaches a certain critical value, the refracted ray lies along the boundary, having an angle of refraction of 90-degrees. This angle of incidence is known as the critical angle which was given to us; 40.0°.  Then we subtitute the value in the equation to get the R.I of the medium.

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.

c) power lifting, will be your answer.
