Ultraviolet light has higher energy compared to visible light, which can excite electrons in certain materials to a higher energy state. When these electrons return to their original state, they release energy in the form of visible light, causing fluorescence.
Yes, urine does not reflect ultraviolet light. Instead, it usually absorbs the ultraviolet light and might fluoresce under certain conditions.
Yes, black light is a real phenomenon. It is a type of ultraviolet light that is not visible to the human eye but can cause certain materials to fluoresce or glow in the dark.
A black light emits ultraviolet (UV) light, which is not visible to the human eye but can cause certain materials to fluoresce. A regular light bulb emits visible light that illuminates the surrounding area.
Ultraviolet radiation causes certain substances to fluoresce by exciting electrons in the substance to higher energy levels, which are then released as visible light.
Black lights do not reveal the presence of germs. They are used to detect certain substances that fluoresce under ultraviolet light, but they do not specifically indicate the presence of germs.

Yes, black light is a real phenomenon. It is a type of ultraviolet light that is not visible to the human eye but can cause certain materials to fluoresce or glow in the dark.
Ultraviolet light can cause certain minerals to fluoresce or emit visible light. By shining ultraviolet light on rocks, minerals that fluoresce can be easily identified and distinguished from other non-fluorescent minerals, aiding in their detection and identification. This property of minerals is harnessed in the field of mineralogy for exploration and research purposes.
Ultraviolet waves of certain wavelengths kill bacteria, tan your skin, and produce the effect known as fluorescence. pg 52 of your textExamples: ultraviolet radiation, visible light.
A black light emits ultraviolet (UV) light, which is not visible to the human eye but can cause certain materials to fluoresce. A regular light bulb emits visible light that illuminates the surrounding area.
Yes, urine can glow under a black light due to the presence of certain compounds such as phosphorus and riboflavin that fluoresce under ultraviolet light.
Ultraviolet radiation causes certain substances to fluoresce by exciting electrons in the substance to higher energy levels, which are then released as visible light.
Fluorite: Fluorite can exhibit a fluorescent response under ultraviolet light, emitting various colors. Calcite: Certain varieties of calcite, such as Iceland spar, can fluoresce under UV light, appearing red, blue, or green. Willemite: Willemite can fluoresce a bright green color under ultraviolet light due to traces of manganese.
Black lights do not reveal the presence of germs. They are used to detect certain substances that fluoresce under ultraviolet light, but they do not specifically indicate the presence of germs.
Exposure to radiation in the ultraviolet region is the most common way of causing fluorescence, but not the only way. Exposure to enough radiation for one electron to absorb two photons can cause fluorescence.
Fluoresce means to emit light or glow when exposed to ultraviolet radiation or certain wavelengths of light. This phenomenon is commonly seen in certain substances like fluorescent markers, minerals, or biological materials.
Yes, a blacklight can make certain colors appear to glow or fluoresce when illuminated, including colored water. This effect is due to the fluorescent properties of certain compounds or dyes in the water reacting to the ultraviolet light emitted by the blacklight.
