Imagine a light ray is aimed directly along the normal line. Use snell's law to describe what happens to the light upon entering and leaving the dish. inclue a sketch

The headlights of a car are 1.3 m apart. What is the maximum distance at which the eye can resolve these two headlights? Take the pupil diameter to be 0.40 cm.

Verify that the critical angle for light going from water to air is 48.6°, as discussed at the end of Example 1.4, regarding the critical angle for lig1it traveling in a polystyrene (a type of plastic) pipe surrounded by air.

(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically involve integrating or extending the concepts presented thus far.) . Of the three converging lenses shown in Figure 9.44, which would you expect to have the shortest focal length? Why?

(Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically involve integrating or extending the concepts presented thus far.) . An observer O stands in front of a plane mirror as shown in Figure 9.80. Which of the numbered locations 1 through 5 best represents the location of the image of the source S seen by the observer? Justify your choice by appealing to the appropriate law(s) of optics.

Calculate the power at the eye when viewing an object 3.00 m away.

No light passes through two perfect polarizing filters with perpendicular axes. However, if a third polarizing filter is placed between the orignal two, some light can pass. Why is this? Under what circumstances does most of the light pass?

Find the radius of a star’s image on the retina of an eye if its pupil is open to 0.65 cm and the distance from the pupil to the retina is 2.8 cm. Assume =550 nm.

Shown below is a ray of light going from air through crown glass into water, such as going into a fish tank. Calculate the amount the ray is displaced by the glass (x), given that the incident angle is 40.0° and the glass is 1 .00 cm thick.

Show that when light reflects from two mirrors that meet each other at a right angle, the outgoing ray is parallel to the incoming ray, as illustrated in the following figure. Figure 25.51 A corner reflector sends the reflected reflected ray back in a direction parallel to the incident ray, independent of incoming direction.
