To draw these ray diagrams, we will have to recall the three rules of refraction for a double convex lens: Any incident ray traveling parallel to the principal axis of a converging lens will refract through the lens and travel through the focal point on the opposite side of the lens.FORMATION OF DIFFERENT TYPES OF IMAGES BY A CONVEX LENS
We will now discuss the formation of different types of images by a convex lens when the object is placed
1. At infinity
2. Beyond 2F
3. At 2F
4. Between F and 2F
5. At the focus F
6. Between the focus F and optical centre C

Hello..
Here is your required answer..
BEFORE MAKING THE RAY DIAGRAMS YOU MUST KNOW THE RULES FOR MAKING DIAGRAMS OF LENSES ARE :-
1- all rays parallel to the principal Axis after refraction pass through the principal focus or seem to come from it.
2- A Ray of light passing through the focus after refraction becomes parallel to the principal axis.
3-A Ray of light passing through the optical centre of the lens after refraction passes undeviated
>IMAGE FORMATION BY CONCAVE LENS<
1- If the position of the object is at infinity then the position of the image appears at the principal focus on the same side as that of the object. the nature of the image is virtual, erect and extremely diminished.
2- If the object is between infinity and the optical centre of lens then the position of the image appear between the principal focus and the optical centre. the nature of the image is virtual erect and diminished.
>IMAGE FORMATION BY CONVEX LENS<
1- If the position of object is at infinity than the position of the image is at the principal focus and in the focal plane and the nature of the image is real inverted and extremely diminished in size.
2- If the position of the object is beyond 2f then the position of image is between f and 2f the nature of the image is real inverted and diminished.
3- If the position of the object is at 2f then the position of the image is at 2f and the nature of the image is real inverted and equal to the size of the object.
4- If the position of the object is between f and the 2f then the position of the image is beyond 2f and the nature of the image is real inverted and bigger than object.
5- If the position of the image is at the principal focus than the position of image is at infinity and the nature of the images real inverted and extremely magnified.
6- If the position of the object is between the optical center and the principal focus and the position of the image is on the same side as that of object and the nature of the image is virtual and magnified.
