Waves 1
The distance between a point on one cycle of a wave and the same point on the next cycle.
What is wavelength?
A wave in which the medium vibrates at right angles to the direction of the wave.
What is a transverse wave?
Sound waves oscillate parallel or perpendicular to the direction in which the wave travels.
What is a parallel?
Sound passes through all of the following except: A) Solids B) Liquids C) Gases D)Air E)Diamonds F) Outer Space
F) Outer Space. Sound needs something to travel through. Space is empty. It is a vacuum.
Sound travels fastest in A) Air B)Water C)Concrete D)Outer space F) Sound travels the same speed in substances
C) Concrete Sound travels fastest in solids. Slowest in gases.
An indication of how high or low a sound is, which is primarily determined by the frequency of the sound wave
What is pitch?
What lens helps farsightness ?
Convex
For waves moving at a constant speed, if wavelength is doubled, what happens to the frequency?
What is frequency is halved?
In a longitudinal wave, areas where the particles of the medium are pulled farther apart.
What are rarefactions?
Mechanical waves need a ______________ to travel through.
What is a medium.
The number of complete cycles in a given time.
What is frequency?
The maximum displacement of the medium from its rest position
What is amplitude?
Who has the lowest wavelength when it comes to sound? Toni Braxton, or Mariah Carey
Toni Braxton
A sound wave can not travel through outer space because of the lack of .
What is matter.
What is the name of the point where all light waves CONVERGE *it's found in a convex lens
focal point
What type of wave comes from the sun
ultraviolet
How does a prism create a rainbow? What wave behavior?
refraction
? = wavelength x frequency
What is speed?
What are compressions?
What happens when light goes from air to water? What wave behavior is this?
slows down, refraction
How are convex lens shaped?
What is thicker in the middle , thinner in on the edges .
What lens help with nearsightdness
Concave
Sound waves are _______ waves.
What is longitudinal?
The more energy a wave has, the greater the ___________.
What is amplitude?
What happens when a wave spreads around a barrier? This is called
Diffraction
