Expert Solution & Answer
To determine
What characteristic lead Maxwell to predict light are electromagnetic waves.
Answer to Problem 1CQ
The speed of the electromagnetic wave is close to the speed of light leads to the conclusion of light is an electromagnetic wave.
Explanation of Solution
Maxwell had studied about the combined effect of electric and magnetic field, found out that the changing electric field could possible to produce changing magnetic field and vice versa. The example of producing electromagnetic wave is an accelerating electric charge.
These electromagnetic wave could travel in space with a speed which is depends on the electric and magnetic property of the surrounding space. When calculated the speed of electromagnetic wave through vacuum it had been found that it is close to the speed of light. This circumstances lead to the conclusion that light is an electromagnetic wave.
Conclusion:
Therefore, the speed of the electromagnetic wave is close to the speed of light leads to the conclusion of light is an electromagnetic wave.

- You may wish to review Sections 16.4 and 16.8 on the transport of energy by string waves and sound. Figure P33.46 is a graphical representation of an electromagnetic wave moving in the x direction. We wish to find an expression for the intensity of this wave by means of a different process from that by which Equation 33.27 was generated.
