Abeam of light travels from a medium with an index of refraction of 1.27 to a medium with an index of refraction of 1.46. if the incoming beam makes an angle of 14.0° with the normal, at what angle from the normal will it refract?

12.15°

Explanation:

Using Snell's law as:

Where,  

 is the angle of incidence  ( 14.0° )

is the angle of refraction  ( ? )

is the refractive index of the refraction medium  (n=1.46)

is the refractive index of the incidence medium (n=1.27)

Hence,  

Angle of refraction = = 12.15°

object 2 because all the other ones are wrong

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.
