Get started for freeThe glass rod of Exercise 34.22 is immersed in oil(n=1.452). An object placed to the left of the rod on the rod’s axis is to be imaged 1.20 m inside the rod. How far from the left end of the rod must the object be located to form the image?
For the situation shown in Fig. 34.3, is the image distance s′ positive or negative? Is the image real or virtual? Explain your answers
If you sit on the beach and look at the ocean through Polaroid sunglasses, the glasses help to reduce the glare from sunlight reflecting off the water. But if you lie on your side on the beach, there is little reduction in the glare. Explain why there is a difference.
Atmospheric haze is due to water droplets or smoke particles (“smog”). Such haze reduces visibility by scattering light so that the light from distant objects becomes randomized and images become indistinct. Explain why visibility through haze can be improved by wearing red-tinted sunglasses, which filter out blue light.
A Spherical Fish Bowl. A small tropical fish is at the centre of a water-filled, spherical fish bowl 28.0 cm in diameter.
(a) Find the apparent position and magnification of the fish to an observer outside the bowl. The effect of the thin walls of the bowl may be ignored. (b) A friend advised the owner of the bowl to keep it out of direct sunlight to avoid blinding the fish, which might swim into the focal point of the parallel rays from the sun. Is the focal point actually within the bowl?
