Polarisation Flashcards
1
Q
What can unpolarised waves do
A
change their plane of oscillation at random
2
Q
what kind of waves can be polarised
A
transverse
3
Q
wave velocity
A
frequency x wavelength
4
Q
time period
A
1/frequency
5
Q
degree to rads
A
degree x π/180 = rads
6
Q
rads to degree
A
rads x 180/π = degree
7
Q
define compression
A
where the particles are at their closest points together
8
Q
define rarefaction
A
where the particles are furthest apart
9
Q
define wavelength
A
centre of compression to next adjacent compression
10
Q
peak pd
A
amplitude x y gain
