Answer 1

Question

Chapter 12, Problem 1Q

(a)

To determine

The explanation for the optical properties of metal.

(a)

Expert Solution

Answer to Problem 1Q

Metals are opaque to visible light.

Explanation of Solution

Metals can absorb visible light. Again, visible can be scattered by the free electron inside the metal. As a result visible light can be easily absorbed by the metals.

Hence, Metals are opaque to the visible light.

(b)

To determine

The explanation for the optical properties of semiconductor.

(b)

Expert Solution

Answer to Problem 1Q

Semiconductors are opaque to visible light however transparent to infrared.

Explanation of Solution

For semiconductor, the valance band can absorb the visible light as it has enough energy. As a result, the electrons can move from valance band to conduction band.

On other hand, the infrared is not has enough energy to get absorb by semi-conductor. Hence,

(c)

To determine

The explanation for the optical properties of insulator.

(c)

Expert Solution

Answer to Problem 1Q

Many insulators are transparent to visible light.

Explanation of Solution

The visible light has not has enough energy to get absorb by insulator. As a result, the electron from valance will not able to move to conduction band. Hence, the visible light can only pass through the insulator, like diamond.

Passage Problems A spiral is an ice-skating position in which the skater glides on one foot with the other foot held above hip level. It's a required element in women's singles figure-skating competition and is related to the arabesque performed in ballet. Figure 5.40 shows Canadian skater Kaetlyn Osmond executing a spiral during her medal-winning perfor- mance at the 2018 Winter Olympics in Gangneung, South Korea. 77. From the photo, you can conclude that the skater is a. executing a turn to her left. b. executing a turn to her right. c. moving in a straight line out of the page. 78. The net force on the skater a. points to her left. b. points to her right. c. is zero. 79. If the skater were to execute the same maneuver but at higher speed, the tilt evident in the photo would be a. less. b. greater. c. unchanged. FIGURE 5.40 Passage Problems 77-80 80.
