1. Incident Ray
2. Reflected Ray
3. Normal Ray
4. virtual and erect
5. Regular Reflection
6. Light get reflected from our eyes and makes the object visible.
7. Images formed by plane mirrors are virtual, upright, left-right reversed, the same distance from the mirror as the object's distance, and the same size as the object.
8. A plane mirror makes an image of objects in front of the mirror; these images appear to be behind the plane in which than mirror lies.
9. Light enters the eye through the transparent cornea, passes through the aqueous humor, the lens, and the vitreous humor, where it finally forms an image on the retina.
10. No image is formed on the blind spot of human eye.
11. An image stays on the retina for about 1/16 of a second. This feature is called persistence of vision. Due to this, when many still images are shown in a sequence; they give the illusion of moving images. Movies and animation are made by exploiting this property of the human eye.
12. Glass and smooth metallic surfaces follow such regular reflection, also called specular reflection. When a beam of light is shone at a particular angle on a very smooth surface.
13. Reflection off of smooth surfaces such as mirrors or a calm body of water leads to a type of reflection known as specular reflection. Reflection off of rough surfaces such as clothing, paper, and the asphalt roadway leads to a type of reflection known as diffuse reflection.
14. There are seven colours in a full spectrum of white light. The various colours of a spectrum in their order, starting with red, are as follows.
15. It is approximately spherical in shape, with its outer layers, such as the outermost, white part of the eye (the sclera) and one of its inner layers (the pigmented choroid) keeping the eye essentially light tight except on the eye's optic axis.
