1) 1. Consider the diagram at the right. Which one of the angles (A, B, C or D) is the angle of incidence?_________ Which one of the angles is the angle of reflection?_______   a) A,B b) A,C c) A,D d) B,C 2) A ray of light is incident towards a plane mirror at an angle of 30-degrees with the mirror surface. What will be the angle of reflection? a) The angle of reflection is 60 degrees b) The angle of reflection is 90 degrees c) The angle of reflection is 120 degrees d) The angle of reflection is 180 degrees 3) Perhaps you have observed the image of the sun in the windows of distant buildings near the time that the sun is rising or setting. However, the image of the sun is not seen in the windows of distant building during midday. Use the diagram below to explain, drawing appropriate light rays on the diagram. a) 3. A ray of light drawn from the sun's position at 6 pm to the distant window reflects off the window and travel to the observer's eye. On the other hand, a ray of light drawn from the 12 pm sun position to the window will reflect and travel to the ground, never making it to the distant observer's eye. b) A ray of light drawn from the sun's position at 7 pm to the distant window reflects off the window and travel to the observer's eye. On the other hand, a ray of light drawn from the 1 pm sun position to the window will reflect and travel to the ground, never making it to the distant observer's eye. c) A ray of light drawn from the sun's position at 8 pm to the distant window reflects off the window and travel to the observer's eye. On the other hand, a ray of light drawn from the 2 pm sun position to the window will reflect and travel to the ground, never making it to the distant observer's eye. d) A ray of light drawn from the sun's position at 9 pm to the distant window reflects off the window and travel to the observer's eye. On the other hand, a ray of light drawn from the 3 pm sun position to the window will reflect and travel to the ground, never making it to the distant observer's eye. 4) A ray of light is approaching a set of three mirrors as shown in the diagram. The light ray is approaching the first mirror at an angle of 45-degrees with the mirror surface. Trace the path of the light ray as it bounces off the mirror. Continue tracing the ray until it finally exits from the mirror system. How many times will the ray reflect before it finally exits? a) The light never reflects before it finally exits the system b) The light reflects once before it finally exits the system c) The light reflects twice before it finally exits the system d) The light reflects thrice before it finally exits the system 5) It is a wave behavior that is the bouncing of light off a surface (or from a surface), which is generally termed as mirror. a) Reflection b) Refraction c) Diffraction d) Absorption 6) These images are images formed by the convergence of light rays from an object. a) Virtual Images b) Real Images c) Real object d) Virtual object 7) It is a law that concerned with the relationship between the angle of incidence and the angle of reflection. a) Law of Refraction b) Law of Reflection c) Law of Diffraction d) Law of Absorption 8) This is a mirror that is commonly found in the largest optical telescopes, are used to collect the faint light emitted from very distant stars. a) Microscope b) Convex Mirror c) Concave mirrors d) Magnifying glass 9) This is a reflection that is defined as light reflected from a smooth surface at a definite angle, whereas diffuse reflection is produced by rough surfaces that tend to reflect light in all directions. a) Diffuse Reflection b) Light Reflection c) Image Reflection d) Specular Reflection 10) This is the angle between the incident ray and the normal ray. a) Angle of reflection b) Angle of incidence c) Incident ray d) Reflected ray
