Waves 1
This type of wave vibrates matter forward and backward in the medium, in the same direction as the wave is moving.
What is a longitudinal wave?
when a wave strikes a surface and bounces off is called
What is reflection?
sound waves cannot carry energy through this
What is a vacuum?
The distance from crest to crest?
What is wavelength?
What type of wave is a sound wave?
longitudinal
Particle oscillate in the direction perpendicular to wave propagation in a ________________ ________
transverse wave?
how a wave bends as it moves from one medium into another
What is refraction?
What is a medium? Give an example
material that mechanical wave needs to travel through.
solid, liquid, Gas
What part of a wave measures/determines loudness?
amplitude
If you were in outerspace, would anybody be able to hear you talk?
No. Require medium to travel through
The wave is taken in the object and turned into heat.
(Refraction, Reflection, transmission, or Absorption)
Absorption
angle of incidence is 40o, what is the angle of reflection
40o
Water waves oscillate in the direction perpendicular to the wave propagation and is an example of
Transverse Waves
What happens when the pitch gets lower?
Frequency becomes lower; energy becomes lower
Sound waves travel the fastest in what medium? The slowest in what medium?
fastest- solids
slowest- gases
Loud sounds would have a _______ _____________
High Amplitude
what will happen when the ray hits the block of clear plastic
Ray bends because it SLOWS down as it travels through a dense, solid material
Sound waves will travel faster in this kind of matter.
What is a solid?
Deep pitch sounds like a tuba would have a _____ ____________
Low frequency
Where the particles of a wave are spread out
Rarefaction
this part of a longitudinal wave Where all the particles of the wave are close together.
What is compression?
What are the Colors of the Rainbow in Order?
R, O, Y, G, B, I, V
What type of wave can travel through a vacuum?
EM Wave
(Radio, Light, UV, Infrared, Microwave)
The number of wavelengths that pass a given point per second.
What is frequency?
The unit of measurement for frequency is ______.
Most people can hear sounds between _____ - ______ _____
hertz (hz)
20-20,000 hz
