Placed the semicircular plastic block on the centre of a blank sheet of paper. Figure 1.1 describes a light across the boundaries of two media with refractive indices ni and nt. Refraction plays a central role to form an objectвЂ™s image in the lens, eye, sound, water and focal length. If you've ever looked in a mirror, you've looked at light that has been reflected by a surface (the mirror). I once had an Optics professor tell us the high reflectivity of metals is due to a very large imaginary part in the index of refraction. Image: When the light rays coming from an object are reflected from a mirror then an optical appearance which is produced by the mirror is called an image. Reflection is just as you might imagine: rays of light that are deflected by a surface (perhaps being sent back toward their source) are reflected. light rays, mirrors, lenses, prisms, etc., is the advanced version of what you As mentioned earlier, the chapter related to light, reflection, and refraction of have studied in the previous classes. The reflection and refraction of light 7-27-99 Rays and wave fronts. The surface does not have to be flat or shiny to reflect light light bouncing off rough surfaces, such as grass or pavement, is reflected in many different directions. вЂњThe PlatformвЂќ is also a grisly, gnarly horror film, one that becomes surprisingly bathed in blood during its action-heavy final act. When a ray of light falls on a mirror at point, it is sent back by the mirror in another direction. Reflection Law of reflection: The angle of incidence equals the angle of reflection (Оё i = Оё r). The angle of incidence is the angle between the incoming light and a line perpendicular to the surface called the normal. Source of light are those objects which give out light. Light is diffused when it reflects from a rough surface. Draw the ray diagram and find the position, size and the nature of вЂ¦ When a ray of light falls on a mirror at point, it is sent back by the mirror in another direction. All these things are possible because of вЂњLightвЂќ and the magical phenomena of вЂњReflectionвЂќ and вЂњRefractionвЂќ. In a slower medium, speed of light is reduced, the wavelength is equally shortened. Whenever a ray of light strikes a surface, at least some of the light is reflected -that is, it bounces off the surface toward a new direction. An object 5 cm in length is held 25 cm away from a converging lens of focal length 10 cm.

Problem on Reflection of Light Through Plane Mirror. After having completed 'How we see' you should be able to use examples from your investigations to do the following: Describe the position, size and nature of the image seen in a plane mirror. Then introduce the lesson, describing books youвЂ™ve read or the activity just completed. interact with the light di erently and impede its passage at di erent rates. Such a body becomes visible when light falls on it. The angles are measured relative to the perpendicular to вЂ¦ 1. Hint: Remember that the sum of the interior angles in a triangle is 180В°.Most of the objects reflect light which falls on them. Calculate the angle, A, that the ray has with respect to the normal line of the second mirror. An incident ray contacts the first mirror at an angle of 65В° to the normal. TR 1.В Two mirrors are joined at a 120В°-angle (as shown in the diagram). On the basis of the investigation that you just performed, state the law of reflection. It relates the angle of incidence to the angle of reflection. The law of reflection is one of the most basic of all laws in optics. Record the values for О in and О out for five different rays when the mirror is at various angles or positions. Adjust the mirror position by clicking and dragging the mirror on the screen.ДЄdjust the position and/or angle of the mirror. The mirror angle can be adjusted using the angle slider ( ). Remember to submit your answers to LAB 1 and LAB 2 to your teacher as part of your Module 5: Lesson 3 Assignment.

О out : the angle between the reflected ray and the normal line О in : the angle between the incident ray and the normal line Normal line: a straight, dashed line drawn perpendicular to the mirror surface at the point of reflection
