Add a B to any waves that are ionising and cause mutations and cancer
Required Practical
Draw a ripple tank. Describe how you can measure the wavelength, frequency
and time period of the waves formed.
Give examples
Transverse Wave
Longitudinal Wave
Waves
What kind of
waves are

Waves
Waves are either t________ or
l___________.
L___________ waves have areas of
c__________ and r____________
with the vibrations p_______ to
the direction of e_____ transfer.
In t________ waves the
v_________ are at r____ a_____
to the direction of e_____ transfer.
Waves
The maximum displacement of a
point on a wave away from its undis-
turbed position is the a________.
The w_________ of a wave is the dis-
tance from a point on one wave to
the equivalent point on the next
wave.
The number of waves passing a point
each s_____ is the ________.
Practice Calculation
Use the equation to calculate the
period of the wave
Period = 1 / Frequency
frequency = 0.1 kHz
Period = ____ (__)

tinuous s_______

travel at the same velocity through
a v_____ 3________ m/s.
Complete the equations
wave speed (m/s) =
Electromagnetic Waves
Electromagnetic spectrum are
grouped in terms of their
w_________ and their f________.
R_____ ____ have the l______ fre-
quency and the l__________
wavelength.
G____ w____ have the _______
frequency and the ________
wavelength.
Colour the word with its meaning
TRANSVERSE
The maximum displacement
of a point on a wave away
from its undisturbed posi-
tion
COMPRESSION The time taken to produce 1
wave (= 1 / frequency)
LONGITUDINAL
A device for viewing waves
on a screen (Cathode Ray
____________)
RAREFACTION
A wave with the vibrations
are perpendicular to the
direction of energy transfer
(e.g. ripples on water)
AMPLITUDE
The distance from a point
on one wave to the equiva-
lent point on the adjacent
wave.
FREQUENCY The unit for frequency
PERIOD
The speed at which the en-
ergy is transferred (or the
wave moves) through a me-
dium
WAVELENGTH When particles are closer
together in a sound wave
HERTZ
A wave with the vibrations
parallel to the direction of
energy transfer (e.g. sound
waves)
WAVE SPEED When particles are further
apart in a sound wave
OSCILLOSCOPE The number of waves pass-
ing a point each second
