Chapter 34: Q. 10 (page 989)

You see an upright, magnified image of your face when you look into a magnifying cosmetic mirror. Where is the image? Is it in front of the mirror's surface, on the mirror's surface, or behind the mirror's surface? Explain.

Short Answer

Expert verified

The magnified image forms behind the surface of the mirror.

Step by step solution

01

definition of mirror

Unlike mirrors, most natural surfaces are rough on the scale of the wavelength of light, and as an outcome, parallel incident light rays are reflected in many different directions irregularly or diffusely.

02

Step 2:Find image

A magnifying cosmetic mirror is a concave mirror with a large radius of curvature and thus a large focal length. It works as follows. When your face is less than one focal length in front of it, a magnified virtual image of your face forms behind the mirror's surface. The figure below depicts a ray diagram of this situation.

Shown from above in FIGURE P34.54 is one corner of a rectangular box filled with water. A laser beam starts 10cmfrom side A of the container and enters the water at position x. You can ignore the thin walls of the container.

a. If x=15cm, does the laser beam refract back into the air through side B or reflect from side B back into the water? Determine the angle of refraction or reflection.

b. Repeat part a for x=25cm.

c. Find the minimum value of x for which the laser beam passes through side B and emerges into the air.

To determine the focal length of a lens, you place the lens in front of a small lightbulb and then adjust a viewing screen to get a sharply focused image. Varying the lens position produces the following data:

Use the best-fit line of an appropriate graph to determine the focal length of the lens.

Some electro-optic materials can change their index of refraction in response to an applied voltage. Suppose a planoconvex lens (flat on one side, a 15.0 cm radius of curvature on the other), made from a material whose normal index of refraction is 1.500, is creating an image of an object that is 50.0 cm from the lens. By how much would the index of refraction need to be increased to move the image 5.0 cm closer to the lens?
