The focal length for red light that strikes a spherical concavelens is $-15 \mathrm{cm} .$ Referring to Figure $27-26,$ will the magnitude ofthe (negative) focal length for blue light be greater than, less than,or equal to 15 $\mathrm{cm} ?$

less than 15 $\mathrm{cm} .$

Okay, so I make a draw off the figure that we have in this problem. And we have our diverging lens and a light rate that divide and a blue wavelength in a rad Waveland. And we can see that these to Waveland has different focal points because they diverge with different angle angles. So let's call the focal point of blue and the focal point of red. Okay, so what? We want to discover the problem. The problem say's that the focal focal length off the red is 15. Same team enters, and we need to say, if the focal lens off the wave off the blue Wave land is going to be less or greater than 15. So as we can see because Ray that verges away from the focal point, it is clear that the focal point off the blue light is closer to the lens, then the focal point for the the red light. Because if we so, if the focal point of the loot the blue is closer, then we can say that the answer to this problem, it's going to me. The focal point of Blue is less then 15 senti mentors, and that's the answer to this problem. Thanks for watching
