Chapter 7, Problem 23E

Interpretation Introduction

Interpretation:

The time taken by light to travel from the Sun to the Earth is to be determined.

Concept Introduction:

Electromagnetic radiation with a certain wavelength is called light.

Electromagnetic radiation is a type of energy that surrounds us. It may lie in the visible region.

Speed is the distance travelled per unit time.

The relation between speed, time and distance is as follows:

$\text{Time}=\frac{\text{Distance}}{\text{Speed}}$

Here, distance is in meters, speed is in $\text{meter/second}$ and time is in seconds.
