Chapter 34: Q. 13 (page 990)

An underwater diver sees the sun50掳above horizontal. How high is the sun above the horizon to a fisherman in a boat above the diver?

Short Answer

Expert verified

The sun is 蟽=31.25掳above the horizon to a fisherman in a boat above the diver.

Step by step solution

01

Determine the sun above the horizon to a fisherman in a boat above the diver:

The equation is,

n1sin蠒1=n2sin蠒2

The data are,

n1=1.00n2=1.33蠒1=?蠒2=40

Solve forsin蠒1:

sin蠒1=n2sin蠒2n1

02

Determine the Value ofσ:

蠒1=sin-1n2sin蠒2

Simplify:

蠒1=56.75掳

Substitute the value:

蟽=90-蠒1=31.25掳

An advanced computer sends information to its various parts via infrared light pulses traveling through silicon fibers. To acquire data from memory, the central processing unit sends a light-pulse request to the memory unit. The memory unit processes the request, then sends a data pulse back to the central processing unit. The memory unit takes 0.5ns to process a request. If the information has to be obtained from memory in 2.0ns, what is the maximum distance the memory unit can be from the central processing unit?

A lightbulb is 3.0 m from a wall. What are the focal length and the position (measured from the bulb) of a lens that will form an image on the wall that is twice the size of the lightbulb?

An object is 40cmin front of a concave mirror with a focal length of 20cm. Use ray tracing to locate the image. Is the image upright or inverted?

The mirror in FIGURE EX34.6 deflects a horizontal laser beam by 60鈭�. What is the angle 蠒?

A concave mirror brings the sun's rays to a focus in front of the mirror. Suppose the mirror is submerged in a swimming pool but still pointed up at the sun. Will the sun's rays be focused nearer to, farther from, or at the same distance from the mirror? Explain.
