What conditions are necessary for total internal reflection to occur? Choose all that apply. What conditions are necessary for total internal reflection to occur? Choose all that apply. n2 must be less than n1 θ1 must be less than θc n2 must be greater than n1 θ1 must be greater than θc How do you know the conditions for this?
Some biological systems can act like an optical fiber. Below is a drawing which illustrates how this might occur. Imagine you have a long, thin cell surrounded by fluid with index of refraction 1.38. The average index of refraction inside the cell is 1.48. Compute the critical angle, theta_crit, for total internal reflection for this system. Show all of your computations. What will the angle of refraction be for ray A (shown below) that has an angle of incidence of...
Calculate the critical angle of total internal reflection (TIR) for the interface between water (n=1.33) and quartz (n=1.55). Express your answer in degrees.
A venturi meter is used to measure the flow speed of a fluid in a pipe. The meter is connected between two sections of the pipe (the figure); the cross-sectional area A of the entrance and exit of the meter matches the pipe's cross-sectional area. Between the entrance and exit, the fluid flows from the pipe with speed V and then through a narrow ''throat'' of cross-sectional area a with speed v. A manometer connects the wider portion of the...
Problem 1: Fibre optics (2 points) Figure 1: Sketches of the geometry of an optical fibre A long cylinder of dielectric material can guide light via total internal reflection. This idea dates back to the 1870s and forms the basis of the modern fibre optics communication technology. As long as the diameter of these fibres is large compared to the wavelength of the infalling light, its wave nature is negligible and we can use Geometric Optics to study the propagation...
Consider a steady flow Carnot cycle with water as the working fluid. The maximum and minimum temperatures in the cycle are 350 and 50 C. The quality of water is 0.891 at the beginning of the heat rejection process and 0.1 at the end. Determine: (a) the thermal efficiency (how much percent). (b) The pressure at the turbine inlet (MPa). (c) The net work output (kJ/kg).
1. Why is it not possible for total internal reflection to occur when a light beam is passing from a medium of low optical density (air) into a medium of higher optical density ( glass or water). Explain fully. 2. When light is incident on an interface between two materials, the angle of the refracted ray depends on the wavelength, but the angle of the reflected ray does not. Why should this be true? Explain fully. 3. Sunlight and star...
Predict how the fluid speed and fluid pressure change as the fluid moves through different sized pipes and undergoes elevation changes. Speed (Increase, decrease, remain the same) Pressure (Increase, decrease, remain the same) Pipe
Water will rise up into a capillary tube. Why, and how is this phenomenon important in nature? Calculate the amount of heat in kJ that is required to heat 20.0 g of ice from -25 degree C to 90 degree C, and sketch a heating curve for the process. The specific heat of ice is 2.11 J/(g. degree C); water 4.18 J/(g. degree C) and the Delta H_fus for water is 6.01 kJ/mol Calculate the amount of heat liberated when...
