Light from a very tiny light bulb passes through a hole of diameter $0.15 \mathrm{m}$ in a dark screen that is $2.5 \mathrm{m}$ away (Fig. $\mathrm{P} 24.1$ ). Assume the light travels as ideal rays as it passes from the bulb, through the hole, and onto a second screen on the far right in Figure $P 24.1 .$ If the light rays illuminate a spot of diameter $0.65 \mathrm{m}$ on the second screen, what is the spacing between the two screens?
