## Laws of Reflection The laws of reflection are as follows: 1. The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane. 2. The angle which the incident ray makes with the normal is equal to the angle which the reflected ray...

## Laws of Reflection The laws of reflection are as follows: 1. The incident ray, the reflected ray and the normal to the reflection surface at the point of the incidence lie in the same plane. 2. The angle which the incident ray makes with the normal is equal to the angle which the reflected ray makes to the same normal. 3. The reflected ray and the incident ray are on the opposite sides of the normal. ## Activity 16.4 **Aim:** To show incident ray and reflected ray are produced by reflection **Materials Required:** * A flashlight * A sheet of paper * Blank white paper * A plane mirror **Method:** 1. Set up a ray box by slinting a side of the box which contains a flashlight so that a thin ray of light is produced. 2. Place a plane mirror on a table covered with a blank white paper. Place the box in front of the mirror as shown in figure 16.6. 3. Switch off the lights of the room. What do you see? 4. Now, try moving the torch slightly left and then right. Observe the reflection. **Observation and Conclusion:** The ray of light falling on the mirror gets reflected back on the white sheet. The more you move the torch towards the reflected ray moves to the right. The ray from Ray Box striking the mirror is incident ray. The ray reflecting from the mirror is the reflected ray. **Aim:** To observe reflection in stainless steel spoon. **Material:** * Stainless steel spoon * A source of light **Type of mirror** * Plane mirror * Concave mirror * Convex mirror
