One dark night, as part of your SEAL tralning, you are scuba diving when your foot gets caught in some machinery underwater. You have a waterproof laser, but the battery Is almost dead, so you'll have to carefully plan how to signal for help. Good thing you took this course! You calculate that your squad will see the laser if the angle In the air (n = 1.00) is 80 degrees. What angle should you choose in the water (n 1.33)7 All angles are defined at the water-air boundary in the usual convention. Assume the surface of the water is flat.

- Using the materials found at the desk (ray box and mirror), design a light path that the criminal could have used to unlock the door. Assume that there are reflective objects scattered throughout the room, so you can place your mirrors wherever necessary. Remember that the ray of light must hit the control panel at a 90 degree angle.A ray of light traveling in air is incident at angle ua on one face of a 90.0° prism made of glass. Part of the light refracts into the prism and strikes the opposite face at point A. If the ray at A is at the critical angle, what is the value of θa?A laser beam with a total power of 22 watts is incident at a normal angle of incidence on a Lambertian surface. How much power reaches a detector with an area of 0.1 cm2 at an angle of 25 degrees located at a distance of 40 cm from where the beam strikes the surface? Please check closest answer. 0.525 mW 0.397 mW 0.247 mW 0.421 mW
- Homework 11, Problem 3White light strikes the left face of a 300-60°-90° glass prism along a normal to the surface (so there is no refraction there). The light moves horizontally through the prism and strikes the right face at an angle of 30.00° to the normal. As the light leaves the prism it is refracted at the right face. DO ALL CALCULATIONS TO 4 SIGNIFICANT FIGURES! What is the DIFFERENCE in the refracted angles for red light (ned = 1.567) and violet (niolet = 1.613)? Find (8, - e,), where e, and e, are the angles of refraction for violet and red light. 313 PMThe figure below shows the path of a light beam through several slabs with different indices of refraction.

A light ray is reflected from a mirror with an angle 15.2° to the normal. What was the angle of incidence? Light passes through a transparent substance at a speed of 2.256 ×108 m/s. Based on the following table, what is the material? index of refraction (n = =) Glass Diamond Substance Ice Water Ethyl alcohol (Click to select) ✓ (Click to select) Ice Diamond Glass Ethyl alcohol Water 1.50 2.42 1.31 1.33 1.36 The wavelength of a monochromatic light source is measured to be 5.06 x10-7 m in a diffraction experiment. (a) What is the frequency? x 1014 Hz (b) What is the energy of a photon of this light? 10-19 JRay optics is based on the assumption that light travels in a straight line. Diffraction effects (observed when light propagates through small apertures/slits or around small obstacles) disprove this assumption. Yet the ray optics assumption is so commonly used in understanding location and several other properties of images in optical instruments. What is the ustification?Light traveling through medium 3 (n3 = 2.4) is incident on the interface with medium 2 (n2 = 2.0) at angle θ. If light does enter into medium 2 but no light enters into medium 1 (n1 = 1.6), what can we conclude about the range of values for θ?
