Under what conditions will a person observe no reflected light? Assume that ttt is the film thickness, mmm = 1, 2, 3,..., nnn is the index of refraction of the film, and λλlambda is the wavelength of the light. Express your answer in terms of the variables m, n, λlambda, and appropriate constants.
Although we do not prove it here, the minimum angle of deviation δmin for a prism occurs when the angle of incidence θ1 is such that the refracted ray inside the prism makes the same angle with the normal to the two prism faces1 as shown. Obtain an expression for the index of refraction of the prism material in terms of the minimum angle of deviation and the apex angle Φ.
A parallel beam of light is incident at 300 to the normal to one face of an equilateral prism (n=1.53), the three faces of which are polished. Trace the path of the light through the prism and find the total deviation produced. For what angle of incidence will the deviation be a minimum?
A beam of light is incident on a hemispherical prism at an angle, theta, as shown in the figure. If the index of refraction of the prism is 1.60, what is the critical angle (in degrees) for no transmitted light out of the bottom of the prism? Assume the index of refraction for air is 1.00 and the index of refraction for the water is 1.33.
When a light ray crosses from water into glass, it emerges at an angle of 30° with respect to the normal of the interface. What is its angle of incidence? I used Snell's Law to find the angle of incidence as 34.8 degrees (rounded to 3 sig fig), using index of refraction for water as 1.333 and for glass as 1.52. However, the answer was marked as wrong. Could you please explain steps for solving to get theta as approximately 42 degrees?
A beam of light reflects and refracts at point A on the interface between material 1 (n1 = 1.33) and material 2 (n2 = 1.66). The incident beam makes an angle of 40° with the interface. What is the angle of reflection atpoint A?
A ray of white light traveling through air enters a triangular prism that has an index of refraction of 1.315 for the red end of the spectrum and 1.345 for the violet end and an apex angle of 72°. If the ray has an angle of incidence of 63° with respect to the normal of the interface boundary, what's the angular separation between the red and violet ends of the spectrum within the prism?
