segment X move as
the wave passes through it?
(1) down, only
(2) up, only

Answer: When the light
hits the surface of the bubble, sof the light is
transmitted and some is reflected
a. When the
pulse
(wave)
reaches a boundary with
another medium, part is
reflected and part is
transmitted (goes through)

b. When a
pulse reaches a fixed,
