Light has a wavelength of 310.3 nm and a frequency of 5.683 × 10¹4 Hz when traveling through a certain substance. What is the refraction index of this medium? Use 2.998 × 108 m/s for the speed of light in a vacuum. Number i Units

8. Three polarizing disks whose planes are parallel and centered on common axıs. The directions of their transmission axes relative to the vertical are respectively: 0 = 17°, 6, = 42°, and 0, 75°. A beam of light polarized along the vertical is incident onto the first polarizer with an intensity of 1o = 20 W/m2, Calculate the transmitted intensity through all three polarizers. W/m2

A beam of green light enters glass from air, at an angle of incidence = 39 degrees. The frequency of green light = 560 x 1012 Hz. Refractive index of 3 x 108 m/s.
