Waves 1 Waves 2 Sound Light Misc
Waves transfer this.
What is energy?
Label the following on the wave
shown.
* wavelength * compression
* rarefaction * amplitude
Wavelength
Compression Rarefaction
Amplitude
When a wave passes from one
medium into another and bends,
it is called this.
What is refraction?
In this type of wave the particles
of the medium move parallel to
the direction of the wave.
What is a longitudinal wave?
In this type of wave the particles
of the medium move
perpendicular to the direction of
the wave.
What is a transverse wave?
This type of wave requires a
medium.
What is a mechanical wave?
When a wave bounces back from
a surface it is called this.
What is reflection?
When a wave bends around an
object, it is called this.
What is diffraction?
When the wavelength of a wave
increases, the frequency does
this.
What is decrease?
speed = wavelength * frequency
This is the frequency of a wave
that travels at a rate of 170 m/s
and has a wavelength of 4 m.
What is 42.5 Hz?
Sound is caused when objects do
this.
What is vibrate?
This part of the wave increases
when the loudness of a sound
increases.
What is amplitude?
This type of frequency produces
a high pitched sound.
What is high frequency?
An echo results from this type of
wave interaction.
What is reflection?
When a siren comes towards you,
the pitch becomes higher because
of this.
What is the Doppler effect?
Our eyes see a blue t-shirt as blue
because this color light is
reflected.
What is blue?
This color of light results when
the light colors red, blue and
green are mixed.
What is white?
The colors of light are different
because this is different for each
color.
What is wavelength?
Draw a diagram that shows how
light is reflected and state the
rule for reflection.
Rule: Angle of incidence equals
angle of reflection.
Angle of incidence Angle of reflection
) )
The figure that shows the correct
reflection below is ____.
Figure A Figure B
Figure B
This part of the electromagnetic
spectrum has the most energy.
What are gamma or cosmic rays?
This color in the visible spectrum
has the least energy.
What is red?
What is wrong with the following
statement?
“Sound travels in transverse
waves.”
Sound travels in longitudinal
waves.
Sound travels fastest in this
medium.
solid
Why is it impossible to hear
sound in space?
Sound is a longitudinal wave and
requires a medium to transfer
energy.
