2. Laser light with a wavelength of 450 nm travelling through water (index of refraction of 1.33) enters a sheet of glass (index of refraction of 1.47). It 4K, 1C enters the glass at an angle of incidence of 450 a) Calculate the speed and angle of refraction of the laser light in the glass b) Calculate the wavelength and frequency of the laser light in the plastic 3..A 12.0 g bullet leaves a rifle with a speed of 1.8 x 10- m/s 4T, 1C a) Calculate the de Broglie wavelength associated with the bullet. b) If the position of the bullet is known to an accuracy of 0.60 cm, what is the minimum uncertainty in momentum.
