![]() In addition, the High School Physics Laboratory Manual addresses content in this section in the lab titled: Mirrors and Lenses, as well as the following standards: (F) describe the role of wave characteristics and behaviors in medical and industrial applications.(E) describe and predict image formation as a consequence of reflection from a plane mirror and refraction through a thin convex lens and.(D) investigate behaviors of waves, including reflection, refraction, diffraction, interference, resonance, and the Doppler effect. ![]() The student knows the characteristics and behavior of waves. Images obtained from the reflection of a plane mirror are laterally inverted.The learning objectives in this section help your students master the following standards: Whenever a light (waveform) travels in one medium that receives a boundary of another medium with a different refractive index, a part of that lightwave always bounces back into the first given medium, known as the reflection of a light ray. Light rays reflect off from an object into our eyes, and the way we see the object is via reflection. Images obtained from the reflection of a plane mirror are laterally inverted (the left is seen towards the right, and the right is seen towards the left).After you see the reflection, the distance between the image from the mirror is equal to the distance between the object and the placement of the mirror.The image obtained after reflection is the same size as that of the object, and both are always equal.The image obtained by a smooth plane mirror is always erect, straight, and not real (virtual).The following are characteristics of images formed by a smooth plane mirror: Characteristics of Images Formed by a Plane Mirror The aforementioned law of reflection states that the angle of reflection (θ r ) will always be equal to the angle of incidence (θ i ). That ray will surely reflect back let that reflected ray make an angle with the normal line to the mirror’s surface this is called the angle of reflection, θ r. That angle is called the angle of incidence, represented by θ i. Think for a moment that the incident ray makes an angle with the normal line to the surface. Here too, the laws of reflection work and are taken into account. Light rays that fall on the flat mirror always get reflected back. A plane mirror is a flat, smooth surface that reflects most of the light received by it. There can always be some part of the same light rays that may/may not pass through the second medium, and this phenomenon is called refraction. The incident ray, reflected ray, and the normal at the point of incidence, are found in the same plane.The angle of incidence is equal to the angle of reflection.This phenomenon is known as reflection, and the rays are called reflected rays. The light ray falling on an object at its surface always bounces back in the same rays. On the other hand, if an object is luminous or giving off light, it further emits rays of light in every direction, and that emitted light goes into the eyes, making the object visible. Light rays reflect off from an object into our eyes, and we see the object via reflection. To easily describe its path theoretically, the concept of a ray of light is used to demonstrate the direction and path travelled by light. The light we see is always travelling in straight lines.
