What kind of electromagnetic radiation causes certain substances to fluoresce?
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.
Which one of the following types of electromagnetic radiation causes certain substance to floursce?
Ultraviolet radiation causes certain substances to fluoresce by exciting electrons in the substance to higher energy levels, which are then released as visible light.
Which one of the following types of electromagnetic radiation causes certain substances to fluoresce a ultraviolet rays b infrared waves c x rays d cosmic rays?

What does fluorecent mean?
It generally means "glowing" - certain elements "fluoresce" (give off a visible light) when hit by electromagnetic radiation, even when the radiation itself is invisible (e.g. UV light). An example is in fluorescent lighting tubes where mercury vapor is electrified to cause a phosphor coating to fluoresce. A slower process called phosphorescence occurs where glow-in-the-dark stickers absorb light and radiate it back slowly as a greenish glow.
How does the earth's atmosphere protect living organism from certain types of electromagnetic radiation?
be far from those radiation
Is light a kind of radiation?
Yes, light is a type of electromagnetic radiation that is visible to the human eye. It falls within a certain range of wavelengths on the electromagnetic spectrum.
What does fluoresce mean?
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.
The Earth's atmosphere filters out certain wavelengths of the electromagnetic spectrum?
Yes, Earth's atmosphere filters out certain wavelengths of the electromagnetic spectrum, such as most ultraviolet radiation and some infrared radiation, before they reach the surface. This filtering is important for protecting life on Earth from harmful radiation.
Which one of the following types of electromagnetic radiation causes certain substances to fluoresce ultraviolet rays infrared waves x rays or cosmic rays?
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.
Where can you find radioactive symbol?
in certain types of radioactive decay processes. it is not electromagnetic radiation.
What has the highest energy of all electromagnetic radiation?
Gamma rays have the highest energy of all electromagnetic radiation. They possess the shortest wavelengths, typically less than 0.01 nanometers, and are produced by nuclear reactions and certain types of radioactive decay. Due to their high energy, gamma rays can penetrate materials more effectively than other forms of electromagnetic radiation.
How are energy and electromagnetic radiation related?
Electromagnetic radiation is one way that energy can be transfered across a distance. EM radiation can be thought of as packets of wave, each called a photon. A photon has a certain amount of energy, which can be found using the formula "E = hf", where 'f' is the frequency of the light, and 'h' is plancks constant (h = 6.626×10−34 Js).
