waves basics
What type of wave is a sound wave?
Longitudinal
What is the peak or top of the wave
crest
Does light reflect, refract, diffract, or all of the above?
All of the above
True or false the speed of light never changes
false
do light waves refract off water
yes
how do waves transfer energy
Waves travel through space to transfer energy
What label is used to measure how many waves there are per second
(HZ)
Black
True or false bigger light waves move faster than smaller ones
False this is a misconception that many people have over light waves all light waves move at the same speed when in the same medium
what is the speed of light
186,000 miles per second
what is a vibration
A fast forward and back motion of a object
what is the height of the wave
amplitude
A pencil looking bent in a glass of water is an example of what light interaction?
Refraction
How do transversal and longitudinal waves move?
Transversal: Perpendicular
Longitudinal: Parallel
What is the difference between transparent and translucent
Transparent lets more light in And translucent lets less light in
what is a medium
a middle state/size, an (in-between/helping) substance like space, or a method of communication of an object
What the amount of waves produced in a set time called
Frequency
What is Reflection?
Waves bouncing off of surfaces
how increasing amplitude change energy?
Increasing amplitude can increase the energy of the wave
example: light waves for instance get bigger when amplitude in waves change
Do light waves reflect of black paper
yes but vary small
how do waves move
moving through air and space making crests
What happens to the light waves when you increase the amplitude
the light would get brighter
Why does refraction happen?
How do you calculate wave speed
speed= wavelength X frequency
