Unit The formation of images by plane mirrors and lenses.

Facts - Image formed on plane mirror -The image formed by the mirror are laterally inverted, upright, same size and virtual. -The image formed by convex lens : 1) For a distance object, the image formed is real, inverted, diminished and on the opposite side of the object. 2) For near object, the object formed is virtual, erect, magnified and the image is formed on the same side as the object.

knowledge Concept -The image formed by the reflection of light.

Student will be able to : Realize the important of reflection and refraction light that help our sight.

-The image formed by a convex lens are always virtual, erect, diminished and on the same side as the object.

-The image formed by refraction of light.

-The light pass through lenses, they converge and meet at a point.

-By drawing rays diagram.

-The formation of image by lenses also can be illustrated by drawing.

The formation of images by optical instruments.

-The pin- hole formed a real inverted and sharp image.

camera. - Telescope used to view object very far away.

- The image formed by refraction of light.

- Image formed by Telescope are enlarge and virtual

Light dispersion.

-Image formed on the eyes is real, inverted and diminished.

- The image formed by refraction of light.

-White light consists of seven different colour components which are red, orange, yellow, green, blue, indigo and Violet.

-Separation of white light into its component colour is known as dispersion of light.

- Formation of rainbow cause by dispersions of light

Light scattering

-The particles reflect and scatter

-Band colour of red, orange, yellow, green, blue, indigo and Violet knows as spectrum. -The process where light is

-Telescope consists of objective lens and eyepiece lens. Objective lens has the longest focal length. Eyepiece lens is magnifying lens.

-Explain the structure and function of various parts of the eye using a camera as analogy. -Compare and contrast the mechanisms in focusing and controlling the amount of light that enters human eyes and a camera. Student will be able to : -State what light dispersion is -Explain through example how dispersion of light occurs.

Student will be able to :

Student will be able to : -Draw a labeled diagram of light through a glass prism.

Student will be able to: -Appreciate the formation of rainbow causes by dispersions of light.

Student will be able to:

the light in all directions. -Blue sky is the effect of light scattering

reflected and scattered in all direction by the particle knows as light scattering.

-State what light scattering is? -Give example of phenomena related to light scattering.

-The red sunset is the effect of light scattering

The addition and subtraction of coloured light.

-Red, green and blue light cannot be produced by mixing light of other light. -Cyan, yellow and magenta light is formed by mixing of light of different colour. -Filter can only allow light of their own colour to pass through them. Other colours are absorbed.

- Red, green and blue light is primary colour.

-Blue + Green = Cyan

-Red + Green = -Cyan, yellow Yellow and magenta light is secondary -Blue + Red = colour. Magenta.

- The colours are absorbed known as subtract.

-Realize the importance of light scattering to blue sky and red sunset formation.

-Explain through examples how scattering of light occurs in natural phenomena. Student will be able to : -Identify primary and secondary colour. -Explain how addition of primary colour produces secondary colour. -Explain the subtraction of colour by coloured filters. -compare and contrast the mixing of pigments with the addition of

Student will be able to : -Draw the overlapping of three primary colour.

Student will be able to : Realize that some colours(secondry colours) can be created from other colours(primary colour)

coloured lights

The appearance of coloured object.

The effect of mixing pigments.

-The appearance of coloured object depend on coloured light

-Subtraction of coloured light.

- The Cone cell is sensitive to blue light, green light and red light.

-Cone cell is the colour vision receptor.

-Rod cell is function in dim light. It is sensitive to shade of grey. - Blue pigment reflects blue light, green and indigo.

-Rod cell is the white and black vision receptor.

-Blue Pigment absorbs red, yellow and orange light. -Yellow pigment reflects yellow, red, orange and violet light. -Yellow pigment absorbs blue and

-Colour of an object is determined by the colour of light shine on it, the colour of light it absorb and the colour of light it reflect.

-Explain the appreance of coloured object under coloured objects.

-Blue + Red = Violet.

Student will be able to : -State what is pigment

-Red + Yellow = Orange. -Blue + Yellow = Green.
