Analysis of the process of coloring objects based on the optical properties of objects

Abstract

Color is a certain spectrum contained in a perfect light (white). The purpose of this study is 1). Can determine the cause of the color of the object (what causes a different object than the other color) 2). Can observe the color that occurs when two or more colors are mixed. The benefit in order to inform readers about what actually causes the color of the object and what if two or more colors are mixed. Mixing colors for color RGB, the colors Red to Green produce colors orange, blue color to produce a color Sian Green, Red color with blue produce magenta, and Red, Green with Blue produces white color. For CMY color mixing, the colors Cyan with yellow produce green color, magenta with yellow produces red color, the color Cyan by Magenta produces blue, and the colors Cyan, Magenta produces yellow Gray (Brown). Color objects can be invisible to the eye because of the reflection of the color of the object illuminated by light.

LED lights of various colors for comprehending the photoelectric effects phenomena

“…Above the LEDs was a black portion that enables connection with a forward-looking light source facing the receiver. Two bushes at the bottom of the front panel may be used to connect an LED utilized as a light source, and a multi-turn potentiometer enables the user to change the current flowing in the LED emitter [28]. The receiving LED's signal may be captured using a BNC at the top of the front panel.…”

Scientific Explanation of the Photoelectric Effect Using Common Objects

“…The LED requires 3 V at 20 mA, resulting in a 60-mW power draw. Each electron obtains a portion of the power provided by this electrical power if it is entirely converted to light and deposited on the photocathode as a wave (Prayogi, Silviana, & Hamid, 2023). The LED illuminates for around 20 μs and then dims for about 45 μs.…”
