Interesting Facts

Yes, I haven't been posting for a long long time : (. but good thing is I've just finished my 8th grade piano exam! yayz! So here is a bunch of info I've been planning to post, but was sitting in my doco folder for 2-ish weeks.

Inverse Square Law... What the...yes sounds weird, but it's the relationship between brightness and distance. Yep, it's got stuff to do with my experiment. Apparently, the law states that the the area in which the light was spread is proportional to the square of the distance. This is why there was such a drastic drop in the light intensity the further the sensor was moved. The light had to spread, so it wasn't so intense in one area...

Okay, next up...the Lux Meter, btw I really don't like Dick Smith. I proclaimed it in Geography. They gave me a lux meter with a dead battery. The only DS i like, eastgardens, of course, replaced it for free! Lucky me...but that's not relevant. The lux meter is a device used to record light intensity. It records stuff in Lux or FC. The light that falls onto the sensor is coverted from light energy to electric energy which calculates an output which is usually shown on video display. Lux meters or light meters are used to measure levels of light in schools, hospitals, production areas, laboratories, and passageways.

Lastly, Stars. My experiment has stuff to do with astronomy, and by measuring light intensity and distance, astronomers can work out the distance of the stars. They do this by investigating the brightness of the stars.

That's all folkies I'll update soon. I hope
