Module 4 Flashcards
What is a radian?
A size of an angle that subtends an arc of a circle, equal to the radius - r
What are some common angles in radian?
How do you convert from degrees to radian (vis versa)
What is a phrase difference?
An angle normally in radians
That calculates the difference in angles between 2 waves
What is a in phase , and the phase difference of each one?
Waves in which the particles meet maximum displacement at the same time
Phase difference = 2 π (360°)
What is a constructive interference ?
Waves with the same amplitude, at the same place and time
What is an anti phase and the phase difference ?
Each point is shifted by half a cycle for the other wave
Phase difference = π (180°)
Destructive interference
Like an anti phase but at the same place at the same time (half cycle ahead )
Phase difference = π (180°)
What is a progressive wave?
- transfer energy without matter
