Question:A layer of benzene (n = 1.50)that is 4.20 cmdeep floats on water (n = 1.33)that is 5.70 cmdeep. What is the apparent distance from the upper benzene surface to the bottom of the water when you view these layers at normal incidence?

Short Answer

Expert verified

The apparent distance from the upper benzene surface to the bottom of the water when you view these layers at normal temperature is -7.085 cm.

Step by step solution

01

Determine the apparent distance

Use the object-image relationship for spherical reflecting surface

Regard both the surfaces as spherical interfaces with radius infinity

Now, for water,

Then,

Therefore, the apparent depth of the water which will work as an object in benzene is 6.4286m.

Now, for benzene: and

Then,

Therefore, the apparent distance from the upper benzene surface to the bottom of the water when you view these layers at normal temperature is -7.085 cm.

The explanation given in Section 33.6 for the color of the setting sun should apply equally well to the risingsun, since sunlight travels the same distance through the atmosphere to reach your eyes at either sunrise or sunset. Typically, however, sunsets are redder than sunrises. Why? (Hint:Particles of all kinds in the atmosphere contribute to scattering.)

Sunlight or starlight passing through the earthโ€™s atmosphere is always ben toward the vertical. Why? Does this mean that a star is not really where it appears to be? Explain.

The laws of optics also apply to electromagnetic waves invisible to the eye. A satellite TV dish is used to detect radio waves coming from orbiting satellites. Why is a curved reflecting surface (a โ€œdishโ€) used? The dish is always concave, never convex; why? The actual radio receiver is placed on an arm and suspended in front of the dish. How far in front of the dish should it be placed?

34.13 Dental Mirror. A dentist uses a curved mirror to view teeth on the upper side of the mouth. Suppose she wants an erect image with a magnification of 2.00 when the mirror is 1.25cm from a tooth. (Treat this problem as though the object and image lie along a straight line.) (a) What kind of mirror (concave or convex) is needed? Use a ray diagram to decide, without performing any calculations. (b) What must be the focal length and radius of curvature of this mirror? (c) Draw a principal-ray diagram to check your answer in part (b).

For a spherical mirror, if s = f , then s' = โˆž, and the lateral magnification m is infinite. Does this make sense? If so, what does it mean?
