Star Brightness

The video tutorial explains the concept of apparent brightness, which is how bright a star appears from Earth. It includes an activity using flashlights to demonstrate how distance affects perceived brightness. The tutorial concludes with questions that help relate the activity to the apparent brightness of stars, including why the Sun appears so bright despite not being the brightest star in the sky.

Describe the activity conducted with the flashlights and its purpose in understanding apparent brightness.

Explain how this activity illustrates why the Sun appears so bright to us when it is not the brightest star in the sky.
