Question
A light year is...Group of answer choicesThe speed light travelsHow long it takes light to get to you from the sunThe distance light can travel in a yearHow many years it takes light to be emittedThe distance between the Sun and Jupiter
Solution
A light year is...Group of answer choices
- The speed light travels
- How long it takes light to get to you from the sun
- The distance light can travel in a year
- How many years it takes light to be emitted
- The distance between the Sun and Jupiter
Step-by-step analysis:
-
The speed light travels: This is incorrect. The speed of light is a measure of how fast light travels, not a measure of distance or time.
-
How long it takes light to get to you from the sun: This is incorrect. The time it takes for light to travel from the Sun to Earth is about 8 minutes and 20 seconds, but this is not what a light year measures.
-
The distance light can travel in a year: This is correct. A light year is a unit of distance that represents how far light travels in one year.
-
How many years it takes light to be emitted: This is incorrect. Light is emitted instantaneously from its source, and this option does not describe a light year.
-
The distance between the Sun and Jupiter: This is incorrect. The distance between the Sun and Jupiter varies as both bodies move in their orbits, and it is not defined as a light year.
Therefore, the correct answer is: The distance light can travel in a year.
