Abeam of light strikes a sheet of glass at an angle of 57.0° with the normal in

1) 1.359, 1.403

2) ,      

Explanation:

The described situation is known as Refraction.  

Refraction is a phenomenon in which a wave (the light in this case) bends or changes it direction when passing through a medium with a refractive index different from the other medium.  

In this context, the Refractive index is a number that describes how fast light propagates through a medium or material, and is defined as the relation between the speed of light in vacuum () and the speed of light in the second medium:

  (1)

On the other hand we have the Snell’s Law:  

  (2)  

Where:  

is the first medium refractive index . We are told is the air, hence

is the second medium refractive index  

is the angle of the incident ray  

is the angle of the refracted ray  

Knowing this, let's begin with the answers:

Using equation (2) according to Snell's Law and   :

Finding :

  (3)>>>Index of Refraction for red light

Again, using equation (2) according to Snell's Law and   :

Finding :

  (4) >>>Index of Refraction for violet light

Here we are going to use equation (1):

Substituting (3) in this equation:

>>>>Speed of red light

Using again equation (1):

Substituting (4) in this equation:

>>>>Speed of violet light

No it is Not because win ratio is differs say Ohio only won 7 out of 7 games and e

was in the playoffs while Alabama won 11 out of 11 games so it is harder to win 11 out of 1a games and it is easier to win 7 out of 7
