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
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.

- The figure below shows, at left, a solid disk of radius R = 0.600 m and mass 75.0 kg. Tu Mounted directly to it and coaxial with it is a pulley with a much smaller mass and a radius of r = 0.230 m. The disk and pulley assembly are on a frictionless axle. A belt is wrapped around the pulley and connected to an electric motor as shown on the right. The turning motor gives the disk and pulley a clockwise angular acceleration of 1.67 rad/s². The tension T in the upper (taut) segment of the belt is 145 N.

He is working on a new trick and has asked you, his star physics student, for assistance. The figure below shows the apparatus he is designing. Cup Hinged end - Support stick A small ball rests on a support so that the center of the ball is at the same height as the upper lip of a cup of negligible mass that is attached to a uniform board of length = 1.89 m. When the support stick is snatched away, the ball will fall and the board will rotate around the hinged end. As the board hits the table, your instructor wants the ball to fall into the cup. The larger the angle 0, the more time the elementary school children will have to watch the progress of the trick. But if the angle is too large, the cup may not pull ahead of the ball.
