Geometric Optics
Which of the following best describes a light ray?
Ray diagrams are visual tools that show the path of light rays. What are they helpful for?
Two mirrors are placed at an angle to each other. A light ray is incident on the first mirror at an angle with respect to the normal. After reflecting off both mirrors, what is the angle between the initial incident ray and the final reflected ray?
What type of reflection occurs when light rays are reflected in many different directions?
A surface is illuminated by a beam of light. It is observed that the light is scattered in all directions, and no clear image is formed. Which of the following best describes the surface?
A light ray strikes a reflective surface and undergoes two successive reflections. The first surface is at an angle of 30° to the incident ray. If the second surface is perpendicular to the first, what is the final angle of reflection with respect to the normal of the second surface?
A light ray is incident on a plane mirror at an angle of 25° with respect to the normal. What is the angle of reflection?
