Question

question 3: Use the lens maker's equation to determine the position of an object if the

image formed by a thin convex lens is 66.7cm from the center of the lens (next to

opposite of the object). The lens has a focal length of 40cm. You have to draw the

object, image, lens type and light rays using a scale (eg 10 cm each

brand)

to. (8pts) Drawing: (3pts) Light rays drawn correctly and to scale; (4pts)

focus, image and object position (and their values). (1pts) Lens type.

b. (2pts) Determine the position of the object

c. (2pts) Calculate lens power

d. (2 pts) Calculate the magnification

and. (2 pts) Determines if the image is real or virtual, magnified or minimized
