Light Intensity Measurement On Sun-Earth System Model Using Logger Pro Light Sensor

Abstract

The measurement of light on the Sun-earth system model has been done using a logger pro and light sensor. The purpose of this research is investigating the relationship between Sun declination with the Sunlight intensity on variety earth model latitude. By Lambert’s Cosine Law, the light intensity that falls on a certain angle can be calculated. On the summer solstice, the highest light energy that was measured on earth model surface occurred on 23.5 degrees north latitude. It was 129.264 candela. The highest light intensity on 23.5 degrees south latitude was 125.907 candela. It has happened on the winter solstice. The light intensity on the equator reaches the maximum compared to the other latitude on the vernal equinox and autumn equinox. There were 115.982 and 111.121 candela, respectively.

Pengukuran Penjumlahan Intensitas Dua Sumber Cahaya Pada Variasi Daya Lampu Menggunakan Light Meter

“…Para siswa dianjurkan untuk memahami dan mempelajari terkait komponen tersebut (Nurfarida, Yusup, & Komariah, 2017). Sehingga perlu digunakan alat peraga untuk mempelajari tentang konsep cahaya khususnya intensitas cahaya yang diukur pada permukaan model Bola Bumi (Sukmawati & Pramudya, 2019).…”
