Three sheets of plastic have unknown indices of refraction. Sheet 1 is placed on top of sheet 2, and a laser beam is directed onto the sheets from above so that it strikes the interface at an angle of 26.50 with the normal. The refracted beam in sheet 2 makes an angle of 31.70 with the normal. The experiment is repeated with sheet 3 on top of sheet 2, and with the same angle of incidence, the refracted beam makes an angle of 36.70 with the normal. If the experiment is repeated again with sheet 1 on top of sheet 3, determine the expected angle of refraction in sheet 3? Assume the same angle of incidence.

The angle of refraction of sheet 3 when sheet 1 is on top of it is

Explanation:

From the question we are told that

     The angle of incidence is  

      The angle of refraction angle for  sheet 1 is  

       The angle of refraction for sheet 3 is  

According to Snell's  law  

Where    are refractive index of sheet 1  and  sheet 2  

       =>  

Also  when sheet 3 in on top of sheet 2

substituting for  

=>    

when sheet 1 in on top of sheet 3

where is the angle of refraction when sheet 1 is on top of sheet 3

substituting for  

=>  

substituting values

=>    

=>  

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
