Use Huygens' Principle to explain how waves propagate, why
incident and reflected waves are equal angles, and why light
changes direction when it refracts
(i)Use the Huygens principle to explain how plane parallel
wavefronts are diffracted at a single aperture.
(ii) Use the principle of superposition to explain how coherent
light emerging from two narrow slits can interfere to produce a
pattern on a distant screen.
In your own words:

1. a) Huygens' Principle. Pick a type of propagation of waves
that light rays don't exhibit. Several to pick in the notes. On a
sheet of paper, graph the starting wavefront of your choice, and
continue with the Huygens' Principle construction of at least 4
additional wavefronts. Does it look like the wave movement can not
be described as a ray?
b) Name and describe one of the three processes mentioned that
allow you to calculate intensity profile on a...
Explain the limitation of the Huygens-Fresnel principle. What
are the two crucial factors that need to be introduced “by hand” in
the equations to make the calculated diffraction pattern relevant
to reality?
Bats use echolocation to navigate and find food by
emitting sound waves that are reflected off their surroundings. If
something nearby is moving, the reflected wave will return to the
bat with a different frequency. Take the temperature of air to be
18 °
a. A bat is hanging from the roof of a cave and emits a sound
pulse every 0.6 seconds trying to find a bug to eat. If it takes
2.1 seconds for a pitch of 1.61...
