The surface that must be curved on the lenses of a diving mask to see clearly both under water and in the air.
Answer to Problem 1OQ
Option (b), on the inner surface only.
Explanation of Solution
The outer surface must be flat to limit the refraction at the outer surface as a result in the charge in medium. The air outside the inner surface will not produce much refraction as there is no change in medium in the inner surface.
Conclusion:
Since the inner surface must be curved on the lenses of a diving mask to see clearly both under water and in the air, option (b) is the correct answer.
Since the outer surface must not be curved on the lenses of a diving mask to see clearly both under water and in the air, option (a) is incorrect.
Since the both surfaces must not be curved on the lenses of a diving mask to see clearly both under water and in the air, option (c) is incorrect.

- A converging lens made of crown glass has a focal length of 15.0 cm when used in air. If the lens is immersed in water, what is its focal length? (a) negative (b) less than 15.0 cm (c) equal to 15.0 cm (d) greater than 15.0 cm (e) none of those answersarrow_forwardFigure P38.43 shows a concave meniscus lens. If |r1| = 8.50 cm and |r2| = 6.50 cm, find the focal length and determine whether the lens is converging or diverging. The lens is made of glass with index of refraction n = 1.55. CHECK and THINK: How do your answers change if the object is placed on the right side of the lens?

After the lens is turned around to interchange the radii of curvature of the two faces, calculate the focal length of the lens for light incident from the left.arrow_forward
- Why is the following situation impossible? Consider the lensmirror combination shown in Figure P35.55. The lens has a focal length of fL = 0.200 m, and the mirror has a focal length of fM = 0.500 m. The lens and mirror are placed a distance d = 1.30 m apart, and an object is placed at p = 0.300 m from the lens. By moving a screen to various positions to the left of the lens, a student finds two different positions of the screen that produce a sharp image of the object. One of these positions corresponds to light leaving the object and traveling to the left through the lens. The other position corresponds to light traveling to the right from the object, reflecting from the mirror and then passing through the lens.
