of?
13) How fast do waves travel?
14) Photons in different waves are
different. How?
15) What 3 ways do we describe waves
and what are the units that go with these terms?
Use
the address below to answer the next questions:
16) What colors make up the visible
light portion of the electromagnetic spectrum?
a. What is the acronym for these
colors?
17) Which color has the longest
wavelength?
18) Which color has the shortest
wavelength?
19) Which color has the highest
frequency?
20) Which color has the lowest
frequency?
21) How is a wavelength measured?
CLICK ON “What are
waves?”
22) What are 2 examples of waves we
can see?
a. We discussed waves that we can
see yesterday in class. These waves are
NOT electromagnetic waves they are _______________________ waves and unlike
electromagnetic waves they require a ____________________________ which is the
matter through which a wave travels.
23) Why is there no sound in space?
24) How are electromagnetic waves
different from sound waves?
25) CLICK ON “What are
electromagnetic waves?”
26) When are electromagnetic waves
formed?
27) In an electromagnetic wave the
magnetic field travels ______________________ to the electric field.
CLICK ON “Different kinds of
electromagnetic waves have different wavelengths.”
28) Waves in the electromagnetic
spectrum vary in size from very long __________________ waves the size of
________________________, to very short _____________________ waves smaller
than the size of the ____________________________________________________.
CLICK ON the “RADIO
WAVES” link at the bottom of the page…
29) For each type of wave, list 3
facts that make it different from the rest:
a. Radio
b. Microwaves
c. Infrared
d. Visible Light
e. Ultraviolet
f. X-rays
g. Gamma Rays
30) Which category of waves has the
longest wavelength?
You
will use the next website to answer the following questions:
31) Activate the tab and tell me what
you see.
CLICK

32) Who noticed the visible light
spectrum first?
33) What causes the waves in a
rainbow to bend?
Close
the “Light Facts” pop-up window and hit NEXT.
34) What do all waves have in common?
35) What is one way we can give water
energy?
36) How do we give energy to the
strings of a guitar?
