The energy of a wave is transferred into a medium; when this occurs light is transformed from light energy to heat energy.

The above statement is correct.

Because:Light is the waves of photons/packets of energy.When it hits a medium.These photons are absorbed by the medium.Atoms of medium will absorb these packets of energy which raise the temperature of medium due to high energy of medium. So light is transformed into heat energy.
