A narrow beam of light is incident on one surface of a plane parallel plate of glass. The index of which is 1.62 and has a thickness of 5 cm at an angle of 45 degrees to the normal, trace the path of light through the plate. What will be the direction of the emergent light if the second surface of the glass is immersed in an oil wich an index of 1.49

The Rayleigh criterion provides a convenient way to describe the theoretical resolution (e.g. an ability to distinguish objects ) of an optical system. The criterion states that two small bright sources of light can be resolved if the first d mìnimum of the image of one source point just coincides with of further apart then the first maximum of another (s Ho Your c below). A converging lens, 28.7 mm in diameter, is used to form images of distant objects. Considering the diffractio lens, what angular separation must two distant point objects have in order to satisfy Rayleigh's criterion? Assume t Here wavelength of the light from the distant objects is 469 nm. Provide your answer in millidegrees (mdeg). STE Exp complexity subscibers Answer: Choose... + Check Finishin Check c

Light enters a container of liquid at an angle of 49° to the normal; the refracted beam makes an angle of 29° with the normal. Calculate the index of refraction of this liquid. Group of answer choices 1.96 1.44 1.56 1.78

In the above figure, theta (the angle the incident ray makes with respect to the vertical) is 26.0 degrees. What is d (the distance between the ray emerging from the bottom of the glass and where the ray would have been if it had continued straight on with no glass to refract it)?

consider the following given. A red laser travelled from air (with an index of refraction of nair = 1.00) to medium A then to medium B as shown below.1. Considering that medium B has an index of refraction of nB = 2.42, what is the angle of refraction ϴ3 (when the laser emerged into medium B) if the angle of incidence is ϴ1 = 60o ?a. 0.35ob. 2.79oc. 21.0od. Not enough information2. From the figure, which of the following statements is true across the three media?a. light travels the slowest in airb. light travels faster in medium A than in medium Bc. light travels the fastest in medium Bd. light travels faster in medium A than in air.

Fig. 1 shows a laser beam incident on a piece of wet filter paper placed on a glass plate whose 'refractive indexglass plate whose refractive index is to be measured (the rays are represented in the figure). Explain what happens anddeduce an expression for ni in terms of R and d. Consider the refractive index of air to be 1.Note: Remember that all light that falls on a reflecting surface always has part of the light reflected, being refracted or not.refracted or not. Moreover, θc in the figure represents the critical angle at which we have the condition of total internal reflection

Determine the maximum angle ? for which the light rays incident on the end of the light pipe in the figure below are subject to total internal reflection along the walls of the pipe. Assume the light pipe has an index of refraction of 1.40 and the outside medium is air.
