Chapter 4, Problem 1QAP

To determine

Whether the statement is true or false.

Answer to Problem 1QAP

The statement is false because energy cannot travel faster than $3\times {10}^8\text{m}/\text{s}$ .

Explanation of Solution

Energy is quantitative property that cannot be created or destroyed; it can only be transferred from one form to another. Various forms of energy are potential, kinetic energy, electric energy, etc. It can travel at very high speed; sound can travel with a speed of $343\text{m}/\text{s}$.

Speed of light is the fastest speed in the universe. Light can travel in any medium or vacuum; it travels at a speed of $3\times {10}^8\text{m}/\text{s}$ in vacuum. Vacuum is a region that contains no matter in it; it means light travels fastest in the vacuum; it slows down when enter into the medium.

Therefore, nothing can travel faster than light in vacuum.

Conclusion:

Thus, the statement is false because energy cannot travel faster than $3\times {10}^8\text{m}/\text{s}$ .
