Do Stars Vary In Their Brightness?

Do Stars Vary In Their Brightness? A star is considered variable if its apparent magnitude (brightness) is altered in any way from our perspective on Earth. These changes can occur over years or just fractions of a second, and can range from one-thousandth of a magnitude to 20 magnitudes. Why do stars differ in intrinsic

Does Light Decrease With Distance?

Does Light Decrease With Distance? There is an inverse relationship between distance and light intensity – as the distance increases, light intensity decreases. … The light energy at three times the distance away is spread over nine times the area, and so on. Why does luminosity decrease with distance? Notice that as the distance increases,

Why Does The Brightness Of A Star Depend On Its Size And Temperature?

Why Does The Brightness Of A Star Depend On Its Size And Temperature? As the size of a star increases, luminosity increases. If you think about it, a larger star has more surface area. That increased surface area allows more light and energy to be given off. Temperature also affects a star’s luminosity. Is the
