The correct statement among the given options is option 'C': The distances the light will travel in one year is one light year which equals to 9.4611012 km.
Explanation:
Light year is a unit of distance, not time. It is defined as the distance that light travels in one year. Let's understand this statement in detail by breaking it down:
1. What is a light year?
- A light year is a unit of distance used in astronomy to measure vast distances in space.
- It is defined as the distance that light travels in one year in a vacuum.
- Since light travels at a finite speed, it takes time for light to travel from one point to another.
2. The speed of light:
- The speed of light in a vacuum is approximately 3,00,000 km/second.
- This means that light can travel about 3,00,000 kilometers in one second.
3. Calculation of the distance in one light year:
- To calculate the distance light travels in one year, we need to multiply the speed of light by the number of seconds in a year.
- One year has approximately 31,536,000 seconds (365 days x 24 hours x 60 minutes x 60 seconds).
- Multiplying the speed of light (3,00,000 km/second) by the number of seconds in a year (31,536,000 seconds) gives us the distance light travels in one year.
- Calculating this results in a distance of approximately 9.4611012 kilometers.
Therefore, the correct statement is option 'C': The distances the light will travel in one year is one light year which equals to 9.4611012 km.
