A big tree fell into the lake and appeared to be broken in the water. How is density of matter involved in this process?
a) Light travels faster through air and slower through water because of different density. When density changes light refracts
b) Light travels faster through water and slower through air because of different density. When density changes light reflects
c) Light travels faster through air and slower through water because of different density. When it changes light is absorbed
d) Light travels faster through air and slower through water because of different density. When it changes, light is transmitted
