When a wave passes through an opening, some of the wave is bent. This phenomenon is called
polarization
reflection
diffraction
refraction
When plane waves pass through an opening, the wave fronts will not change much if the opening is
the same size as the wavelength
wide compared to the wavelength
narrow compared to the wavelength
none of the above
Which of the following is a consequence of the refraction of light?
rainbows
mirages
internal reflection
all of the above
A beam of light travels fastest in
air
water
plastic
glass
The spectrum produced by a prism or a raindrop is evidence that the average speed of light in the material depends on the lights
transmission qualities
color
wave nature
particle nature
Different colors of light travel at different speeds in a transparent medium. In a vacuum, different colors of light travel at
the same speed
different speeds
both a and b
none of the above
The effect that we call a mirage has most to do with
reflection
refraction
diffraction
interference
When you see a wet spot mirage on the road in front of you, you are most likely seeing
water
hot air
a figment of your imagination
sky
You can hear noises a long distance away over water at night because
of lowered temperature
water conducts sound better at night
sound is reflected off water more efficiently at night
of refraction of sound in air
Refraction occurs
when a wave changes speed
only at a wave front
at any unpredictable time
only with light waves
Refraction is caused by
different wave speeds
more than one reflection
displaced images
bending
