Worksheet time: 34mins
What is the frequency of a wave?
# of oscillations produced in a certain amount of time
The distance the wave oscillates from it's resting position
The lowest point of a transverse wave
Resting point of a wave - no wave movement
What is the amplitude of a wave?
Where there is no wave movement
The distance the wave oscillates from it's resting position
A disturbance that transfers energy from one place to another
The distance between two corresponding parts of a wave
If the wavelength of a wave increased, what would happen to the frequency?
decrease
increase
stay the same
What property of this wave is represented by the letter "A"
amplitude
crest
trough
wavelength
The units of frequency are...
metres
seconds
Hertz
degrees
Light is an example of a transverse wave
True
False
Sound is an example of a transverse wave
True
False
Which of the following statements describes the period of a wave?
Number of waves per second
Distance from crest to crest
Distance from resting position to top of the wave
Time taken to produce one wave
One use of radio waves is...
Broadcasting and communications
Heating
Observing internal structure of objects
Sterilising food and medical equipment
The following image demonstrates...
Reflection
Refraction
Interference
Diffraction
Which type of wave as oscillations that are parallel to the direction of energy transfer?
Transverse
Light
Longitudinal
S-Wave
A material has a high optical density. What will this do to the speed of light when it enters?
Speed it up
Slow it down
Stays the same
Electromagnetic waves are made up of oscillating..
particles.
protons.
electric and magnetic fields.
electric fields.
Which type of radio waves is reflected off the ionosphere?
Long-wave
Short-wave
Which type of radio wave can diffract (bend) around curved surfaces such as hills?
Long-wave
Short-wave
How are Electromagnetic waves different from Mechanical waves?
EM waves have very short wavelengths
EM waves transmit energy instead of matter
EM waves can travel through the vacuum of space (without particles)
EM waves can change direction by reflection
Which is true about the speed of radio waves compared to light waves? They are...
less energy & frequency, but still the SAME speed as the speed of light (300,000,000 m/s)
less energy & frequency, so LESS than the speed of light (300,000,000 m/s)
smaller wavelength, so LESS than the speed of light (300,000,000 m/s)
more energy & frequency, so MORE than the speed of light (300,000,000 m/s)
To calculate the frequency of an electromagnetic wave, you need to know the speed of the wave and its
wavelength.
intensity.
refraction.
amplitude.
A radio wave has a frequency of 12.0 x 106 Hz. Find its wavelength. (the speed of radtio waves in air is 3.0 x 108 m/s).
