← A cabinet maker tests a new clear plastic of refractive index 1.47 with a lamp in air. At what angle of incidence will the glare reflected from the plastic be completely plane polarised?The molecules of a clear gas are far smaller than the wavelength of light, and they scatter light in proportion to 1/λ⁴. Compare two colours. How many times as strongly is light of wavelength 530 nm scattered, as light of wavelength 700 nm? →
