- Light traveling horizontally enters a right-angle prism as shown in the figure below. The index of refraction of the prism is n = 1.6, and it is surrounded by air. 45° 02 Determine the exit deflection angle 02. Express your answer in degrees, to at least one digit after the decimal.In the drawing, a laser is fired from point P in the center of the open side of the square room. The laser is pointed at the mirrored wall on the right. At what angle of incidence must the light strike the right-hand wall so that, after being reflected, the light hits the left corner of the back wall? (Ignore the point marked "target.") Give your answer to three significant figures.A physicist directs a laser beam through a transparent medium, toward one surface of an equilateral prism. (The beam travels, and remains in, the plane of the page.) Incident on Surface 1 at an angle ?1, the beam then encounters Surface 2 from within the prism. If the angle of incidence at Surface 2 equals ?c , the critical angle for this prism, what is the original incidence angle, ?1 (in degrees)? The critical angle in this case is ?c = 40.5°. 40.5° 40.5° A prism in the shape of an equilateral triangle is shown. The triangle is upside down such that the base of the triangle is at the top of the figure and the apex is at the bottom. A laser beam comes in from the top left, moves down and to the right and is incident on the center of the base of the triangle. This surface is labeled Surface 1. The incident beam makes an angle of ?1 with the vertical. Within the prism, the beam continues to move down and to the right but at a slope which is steeper than the initial beam. It is incident…
- For this problem, I know the answer is B but I do not know how to get there. Seeing the steps and equations would be much appreciated. Thank youAn object pin is placed at the front of a circular container of water as shown in the top-view figure below. The refractive index of water is 1.3. The center of the container is marked with a x. (a) Draw a neatly labeled and somewhat correct ray diagram and determine the location of the image pin as percevied by the observer X. (b) If the refractive index of the liquid were to decrease, would X perceive the location of the image pin to move closer to them, farther from them, or remain unchanged? Please explain your reasoning. Object pin, top view X Observer Container of water, n = 1.3I already know the answer to this practice problem, and it is shown is the image. I do not know how to get to the answer though, so seeing the steps and equations would be much appreciated.
