Waves and Light
Unit 8
In this unit we will study wave motion as a means of transmitting energy. We will see that
sound is transmitted by longitudinal waves. Through the work of Christian Huygens
(1629-1695) and Thomas Young (1773-1829), we are shown that the reflection, refraction,
diffraction, and interference of light can also be explained by assuming that light is
transmitted by means of waves.
