Chapter 26 Geometrical Optics

Chapter 26 Geometrical Optics. The Reflection of Light. If a stone is dropped into a pond, circular waves emanate from the point where it landed. Rays, perpendicular to the wave fronts, give the direction in which the waves propagate.

Geometrical Optics

Geometrical Optics. Huygens Principle . Light can be treated as a series of RAYS with POINT SOURCES Thus, light can be treated as a plane wave (just as sound was, when it was far enough from the source). The Reflection of Light.

Light and the Electromagnetic Spectrum

Light and the Electromagnetic Spectrum. Light as Energy. There is much evidence in our world that light is a form of energy. . Electromagnetic Spectrum. Electromagnetic waves include visible light and several other types of waves. Arranged in order, they form the electromagnetic spectrum. .

Seeing Things Image Location in Plane Mirrors

Seeing Things Image Location in Plane Mirrors. Seeing Things Image Location in Plane Mirrors. We see the object when looking directly at it because rays of light go from it straight into our eyes.

Plane Mirrors

Plane Mirrors. The Ray Model of Light. Light sources radiate light in all directions. The direction in which light travels is represented by lines with arrows (rays) on diagrams. . The basic property of light is that when it travels within the same medium, it moves in straight lines.

OBJECTIVES

OBJECTIVES. 1) Trace light rays as they reflect from a plane mirror. 2) Draw conclusions about the law of reflection. 3) Identify angle of incident and angle of reflection. 4) State the laws of reflection of light. Using ray boxes. Reflection. Draw around the mirror. Reflection. normal.

Reflection of Light

Reflection of Light. Regular Reflection of Light. The reflection of light from smooth, shiny surfaces, such as mirrors, is called regular reflection. Light that travels towards a mirror is called the incident light. Light that is reflected from a mirror is called the reflected light .

Reflection & Mirrors

Reflection & Mirrors. Recap:. Diffuse reflection: gives a blurry image (or none at all). Specular reflection: gives a clear image. Mirror types: PLANE CONVEX CONCAVE . Plane Mirrors. The image formed by plane mirrors can only be seen behind the mirror.

Reflection and Mirrors

Reflection and Mirrors. Seeing Yourself. Law of Reflection. The law of reflection states that the angle of incidence is equal to the angle of reflection. Definitions. Incident ray is the ray moving toward the surface Reflected ray is the ray moving from the surface

Reflection

Reflection. LIGHT Principles of Physics. Representing Light Waves. It is impossible to see the actual wave shape (crests and troughs, etc) of a light wave Instead we draw straight lines, called RAYS , that show the direction and path followed by the light. Representing Light Waves. Rays:

Mirrors why bother?

Mirrors why bother? . 3 types of mirrors. Flat (plane, infinite). Concave (caved in, converging). Convex (vexed out, diverging). Plane Mirrors. Is this kind of plane mirror possible?. Curved Mirror Terms. focal point= r/2 (horizontal light focuses here).

Mirrors and Reflection. Reflection. The change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. . Law of reflection.

Plane Mirrors

Plane Mirrors. Mirror Image. Viewing a mirror shows an image. Light rays from an object reflect from the mirror. The eye traces the rays back to an image. Plane Mirror. The law of reflection applies to each ray from the source at the mirror.
