Question: An outdoor circular fish pond has a diameter of 4 00
An outdoor circular fish pond has a diameter of 4.00 m and a uniform full depth of 1.50 m. A fish halfway down in the pond and 0.50 m from the near side can just see the full height of a 1.80-m-tall person. How far away from the edge of the pond is the person?
Answer to relevant QuestionsFor total internal reflection to occur inside an optic fiber as shown in Fig. 22.29, the angle u must be greater than the critical angle for the fiber–air interface. At the end of the fiber, the incident light undergoes a ...White light passes through a piece of crown glass and strikes an interface with air at an angle of 41.15o. Assume the indices of refraction of crown glass are the same as given in Exercise 44. Which color(s) of light will be ...In Exercise 47, if the angle of incidence is too small, light will not emerge from the other side of the prism. How could this happen? Calculate the minimum angle of incidence for the red light so that it does not emerge ...What is the cause of spherical aberration?
