Light and Sound Flashcards
What is the other type of wave (not longitudinal wave) that goes perpendicular to the direction the wave is moving?
Transverse wave
where is the rare fraction in a longitudinal wave?
where the matter is the furthest apart
what kind of wave is this?
I I I I I IIII I I I I I
longitudinal wave
Does light or sound travel in longitudinal waves?
yes, sound does
When does refraction occur?
When light passes through another medium and it’s speed changes
What kind of wave does light travel in
transverse waves
What is the name of the top of a transverse wave?
A crest
Where does the compression occur?
Where the medium is really compact and dense in a longitudinal wave
How do you measure light reflection?
Write a normal perpendicular to the surface, and measure the angle from that to the reflection ray.
What is an incidence ray?
The ray before the reflection occurs
how many Herz is one mega Herz?
1,000,000, dont think they’ll ask this tho
What is the frequency of a wave? (Hz)
How many waves pass through a point in one second.
What is the wavelength?
The length of a wave, measured from one crest to the other, or one compression to other.
what is wave amplitude?
The distance between the crest and the normal (the line that goes straight from the strating point)
