Question

Imagine you are an astronomer studying the Sun, and you are looking at the Sun through a telescope -- with a strong filter to protect your eyes of course. While you are gazing at the Sun, you see a "flare" on the SURFACE of the Sun -- a small but violent eruption that simultaneously emits a lot of light at ALL wavelengths, from radio waves to gamma rays. How long after you see the flare until the Earth is bathed in the dangerous x-rays and gamma rays from this flare? Group of answer choices

Answer 1

`4.98*10^(2) s`

Step-by-step explanation:

Light has an speed of

`v= 3*10^(5) km/s`

The distance from Sun to Earth

`D=1au =1.496*10^(8)  km`

The time light , gamma, and X rays take to reach earth is the same, and it is calculated :

`t=(D)/(v) =(1.496*10^(8))/( 3*10^(5) ) =4.98*10^(2)`s

About 8.3 mins

Hope my answer helps

Have a nice day!
