Chapter 9: Q62. (page 478)

Earth is an average $1.496 脳 10^{8}$ kilometres from the Sun. If light travels $3 脳 10^{5}$ kilometres per second, how long does it take sunlight to reach Earth?

Short Answer

Expert verified

The time taken by the sunlight to reach Earth is498.66 seconds.

Step by step solution

Step 1. Given Information.

Given, Earth is an average $1.496 脳 10^{8}$ kilometres from the Sun and light travels $3 脳 10^{5}$ kilometres per second. The time taken by the sunlight to reach Earth is to be determined.

Step 2. Explanation.

Here the given distance between Earth and Sun is $1.496 脳 10^{8}$ kilometers.

And, the speed of light is $3 脳 10^{5}$ kilometers per second.

Time taken is given by the ratio between distance and speed.

$\begin{array}{l} time = \frac{distance}{speed} \\ t = \frac{1.496 脳 10^{8}}{3 脳 10^{5}} \\ t = \frac{1496 脳 10^{5}}{3 脳 10^{5}} \\ t = 498.66 \end{array}$

Step 3. Conclusion.

Hence the time taken by the sunlight to reach Earth is 498.66 seconds.
