Waves Flashcards
1
Q
wave speed =
A
frequency x wavelength v = f x λ
2
Q
law of reflection: angle of incidence =
A
angle of reflection
3
Q
law of refraction: refractive index=
A
n = sin i/sin r
where i=angle of incidence, r=angle of refraction
4
Q
total internal reflection: refractive index
A
n = 1/sin c
5
Q
frequency=
A
1/Time period
