When light moves from one medium to another, it is refracted. If it moves from a medium with refractive index n1 to one with refractive index n2, with an incidence angle to the surface normal of θ1, the refraction angle θ2 can be calculated from Snell's law.
The Snell's law states that the ratio of the sines of the angles of incidence and refraction of a wave (in this case beam/light) are constant when it passes between two given media.

Given that a <span>laser travels from glass to water at an angle of 35° with the normal, </span>

<span>. If water has an index of refraction of 1.33 and glass has an index of refraction of 1.52, then we have:

Answer:
<h3>The translation statement for the given equation

is " Three-fourths of a number minus twelve is the same as twelve. "</h3>
Step-by-step explanation:
Given equation is 
<h3>To find the statement which could be a translation of the given equation :</h3>

- The above equation can be written as
- Three-fourths of a number x minus twelve is equal to twelve.
<h3>Therefore the translation statement for the given equation

is " Three-fourths of a number minus twelve is the same as twelve. "</h3>
The option is <u> " Three-fourths of a number minus twelve is the same as twelve. "</u> correct
It doesn't have to be called width
So just use the formula.
A=h×w
A=2×8.5
A=17
The area of the rectangle is 17 meters
