a disturbance caused by a vibration and transfers enegry
wave
when light bounces off a surface
reflection
the bending of light when it enters new matter
refraction
tranverse wave
sound
what happens when a rock is dropped in water
waves travel away from the spot the rock hits
compressional
what can carry lots of information and move at the speed of light
electromagnetic waves
when light hits an uneven surface and scatters
diffusion
why does a pencil seem to bend when its in water
refraction
Identify the high and low pitch waves
top low pitch
bottom high pitch
when sound waves travel through air, air particles
vibrate outward in all directions
energy
which baritone makes a high volume
the distance between one peak and the next of a wave
wavelength
the number of cycles a wave completes in a period of time
frequency
opaque- person
transluscent- wax paper
transparent- window
where can you not hear sound
a student puts water in a plastic tub. The student moves the pencil up and down to make waves. How could the student make waves with more energy
move the pencil faster
what does this show
reflection of light
objects make sound waves when they
an object that vibrates faster forms a sound wave with _________ frequency
what does this show
transmission of light
height or strength of a wave
amplitude
an object that vibrates slower forms a sound wave with a ________ frequency
lower
