Waves

Question 1

Whats the equation linking wave speed frequency and wavelength

Answer 1

wavespeed (m/s) = Frequency (Hz) X wavelength (m)

Question 2

what’s the equation linking frequency, 1 and period

Answer 2

frequency (Hz) = 1/period (s)

Question 3

what’s the equation linking refractive index, sin angle of incidence and sin angle of refraction

Answer 3

refractive index = sin angle of incidence / sin angle of refraction

Question 4

what’s the equation linking sin critical angle, 1 and refractive index

Answer 4

sin critical angle = 1 / refractive index
