A ray of light traveling in air is incident on the flat surface of a piece of glass at an angle of 65.9° with respect to the nor
stich3 [128]

Answer:

n_{glass} = 1.6

Explanation:

\theta _{i} = Angle of incidence = 65.9°

\theta _{r} = Angle of refraction = 34.8°

n_{air} = Index of refraction of air = 1

n_{glass} = Index of refraction of glass = ?

Using Snell's law

n_{air} Sin\theta _{i} = n_{glass} \theta _{r}

(1) Sin65.9 =  n_{glass} Sin34.8

n_{glass} = 1.6

Is the appearance of a light wave changed as it is aborted?
Sonbull [250]
Light waves are never 'aborted'. 

They can be 'absorbed', and I think that's what you mean. 
It's what happens when light hits something or goes into it,
and never comes out. 

"Absorb" just means "soak up".  When a light wave hits something and
gets soaked up in it, it's gone, and never comes out the other side.

The light wave certainly gets changed ... it no longer exists.

The object that absorbs it also gets changed.  It soaks up the energy
in the light wave, and it has a little more internal energy (heat) than it
had before the light hit it.
