speed and wavelength
speed and frequency
If light is traveling from air to water and has an angle of REFRACTION of 30 degrees, what is the angle of INCIDENCE? (n=1 air, n=1.33 water) Which is set up correctly?
(1)(sin30) = (1.33)(sinƟ)....
.....sinƟ = (1)(sin30) / 1.33
(1)(sin30) = (1.33)(sinƟ).....
.....sinƟ = 1.33 / (1)(sin30)
(1)(sinƟ) = (1.33)(sin30)......
....sinƟ = (1.33)(sin30) / 1
(1)(sinƟ) = (1.33)(sin30).....
.....sinƟ = 1 / (1.33)(sin30)
