Question

Each square is 0.50 cm along the horizontal direction. Use the diagram to answer the following questions, a) Using only the ray shown, decide what type of lens is this (convergent or divergent). b) What Is the focal length of the lens. c) In the diagram, locate the position of the image by drawing the other two principal rays. d) Using the analytical relations or formulas, calculate the lens-image distance s', and compare this result with the graphical solution from part c). Express your answers to two significant figures.

Explanation / Answer

a) lense is a convergent lense becasue the ray became straight after passing the lense its mean that the ray came out after passing the focus point.

b) The position of bug is the focal point and the focal lenth will be

f = 13(0.50) cm = 6.5cm

d) According to the foumula

1/f = 1/p + 1/q

1/q = 1/p -1/f

q = pf / f-p

q =(3.5)( 6.5) / 3.5+6.5

q = 2.2cm
