What angle separates the directions of propagation of the 580 nm wavelength and the 550 nm wavelength parts of the beam as they enter the air?
The 580 nm wavelength and 550 nm wavelength parts of the emergent light beam are incident on a surface that is perpendicular to the axis of propagation of the emergent beam. At the surface, the 580 nm wavelength and 550 nm wavelength parts of the beam are separated from each other by 1.00 mm. What is the distance between the point of emergence of the beam and this surface?
A ray of -m light goes from air into fused quartz at an incident angle of . Determine at what incident angle -m light must enter flint glass to have the same angle of refraction. Use a value of 1.458 for the refractive index of quartz and use a value of 1.66 for the refractive index of flint glass.
At what angle is m wavelength red light in the beam refracted? Use 1.33 for the refrative index of red light.
At what angle is m wavelength violet light in the beam refracted? Use 1.34 for the refrative index of violet light.
