Transcript text: How many times brighter is a 1st magnitude star than a 6th magnitude star?
Solution
Solution Steps
Step 1: Understanding the Magnitude Scale
The magnitude scale in astronomy is a logarithmic scale used to measure the brightness of stars. A difference of 5 magnitudes corresponds to a brightness factor of 100.
Step 2: Calculating the Brightness Difference
To find how many times brighter a 1st magnitude star is compared to a 6th magnitude star, we use the formula:
\[
\text{Brightness factor} = 10^{(m_2 - m_1)/2.5}
\]
where \( m_1 \) and \( m_2 \) are the magnitudes of the two stars.
