Why does light refract when it encounters the glass in a lens?

Question 6 options:

a.because it speeds up, which causes it to bend


b.because it slows down, which causes it to bend


c.because it hits a dense medium, which causes it to bounce off


d.because it gets absorbed, which causes it to lessen in intensity

Respuesta :

The answer is C, because it hits a dense medium, which causes it to bounce off.  

Hope I helped.  :)

the answer is b not c. Light hits the glass in a lens because it slows down, which causes it to bend. The material of a lens is more optically dense than the air it is traveling from.
