fluorescence
Each colored line in hydrogen's emission spectrum corresponds to a specific transition of an electron between energy levels in the hydrogen atom. The wavelengths of these lines are unique to each transition, creating a distinct pattern that can be used to identify elements and their energy levels.
When heated, each element produces a series of thin colored lines called an emission spectrum. This unique pattern of lines is used to identify the elements present in a sample based on their characteristic wavelengths of light.
The fact the solution is colored means that it absorbs (or interacts at least) with visible (since you can see it!). Generally such compounds are characterized using visible light, but also ultraviolet (UV) and infrared (IR) which are the two regions of the electromagnetic spectrum adjacent to visible light. This type of analysis is generally called UV/visible spectroscopy (although it frequently also extends into the near IR region).
Solid potassium dichromate is kept in colored bottles to prevent exposure to light, which can cause it to decompose. The compound is light-sensitive and may undergo a reaction, making it less effective or even unsafe to use. Keeping it in colored bottles helps to protect its stability and prolong its shelf life.
Factors that affect the temperature of soil include sunlight exposure, soil color, moisture content, soil composition, and airflow. Sunlight exposure can warm up the soil, while dark-colored soil absorbs more heat than light-colored soil. Moisture content affects how well the soil retains heat, with wet soil typically having a lower temperature. Soil composition and airflow can also influence soil temperature by affecting how quickly heat is transferred within the soil.
Pigment that protects from the ultraviolet light is called melanin. This is science.
The emission spectrum of elements is a unique pattern of colored lines produced when an element is heated or excited. Each element has its own distinct emission spectrum, which can be used to identify the element.
I think its a tan A sunburn is radiation burned skin damaged by too much ultraviolet radiation from the sun. The skin turns red and becomes painful too touch. A more gradual exposure to the sun or the use of sunscreen allows the skin to start manufacturing melanin which protects the skin from sunburn The melanin make the skin darken to what we refer to as a suntan.
Sunscreen is the colored substance that helps to keep the skin from burning by absorbing or reflecting UV rays from the sun.
Melanin
any substance (colored or not) with a density less than 1 will float on water
Exposure to light can cause colored fabrics to fade over time, reducing their longevity.
Fluorescence. It happens when atoms' electrons absorb light at one frequency and emit at other (usually lower) frequencies. Sometimes two photons are absorbed by the same electron, and emitted as a single higher frequency, but this is not common.

Emission spectra consist of discrete, colored lines at specific wavelengths, corresponding to the emission of photons as electrons transition from higher to lower energy levels. Each element has a unique emission spectrum due to its specific electron configuration and energy levels. Emission spectra are useful for identifying elements present in a sample and are commonly used in analytical chemistry and astronomy.
