NSES Content Standard B
Physical Science: Transfer of energy Grades 5-8, page 155 Light interacts with matter by transmission (including refraction),
absorption, or scattering (including reflection). To see an object, light
from that object--emitted by or scattered from it--must enter the eye.

Grades 9-12, page 92
Waves can superpose on one another, bend around corners, reflect off
surfaces, be absorbed by materials they enter, and change direction when
entering a new material. All these effects vary with wavelength. The energy
of waves (like any form of energy) can be changed into other forms of energy.
